Parser refactor (#43)

* rename and add new examples per template

* Remove unrequired plugin

Not required in fact.

`gitbook-plugin-ace` is required only if user pass "ace" or "acefull" to the template
option. It is specified in the README.md.

* Update readme

* Add check plugin load order

- Add winston-color for color logs
- produce a warning if gitbook-plugin-ace is not loaded (ace template won't work)
- produce an error if gitbook-plugin-ace is loaded but before include-codeblock

* update log message

* update travis tests

* Fix Readme

* use path package

* separate ace check

* Improve example

* Improve custom example

* Improve default example

* Refactor parser

- Should be cleaner and less error prone
- Define global book option map, and possible key-value map (same as in
  readme).
- Use immutable Map to avoid unwanted changes.
- Pass `template`, `unindent` function arguments into the key-value map
  directly for consistency.
- Systemize key-value argument for each functions.

* Add inline code remark

- include-codeblock does not work if we use it inline.
for example:

```
blabla [import](fixtures/test.js) blablabla
```

NB: we might have some works to add newline before and after block.

* Update tests

* Remove log

* up package version

* Add multi snippets feature

* Update test using templates from map

* Add support equal char for

* Fix template quotes + up version 3.1.0 major

- It seems ace does work with boolean instead of strings for booleans
type keys.
- Update version 3.1.0, changes will be major

* Update readme

* Rename options to avoid confusion

* Separate options maps

Options can be set globally or locally:

- Set an immutable default map book.json global plugin options
- Set an immutable default key-value map for local command options.
- Add functions to check map types

* Clean option file

* Move convertValue

* Refactor parser

- Refactor parseVariableFromCommand regex to be more comprehensible.
- Handle boolean type
- Add parse check depending on the value type and convert the parsed
  value to its type (JSON.parse)
- Fix type check. Default l/g options map should not have `undefined`
  value as value type is deduced from the map.

* Update marker check with empty string

- Update check for empty string which is not valid.

* Update package options

- Add default value options in package.json directly. Options map are
  updated from it.
- Fix package default type to be consistent (avoid string). Now boolean
  is `true` and not `"true"`.

* Revert options get

* Update + new test

- Update parse tests to handle better tests (simpler & different case).
- Add test for multiple markers

* Refactor lang key

break backward compatibility

- set hardcode lang as book option, or command option.
- Remove `lang-javascript` and use standard key-val format
`lang:"javascript"` or `lang:".js"`. If lang or extension (via lang) is not set,
 then lang is determined rom file extension.
- Create template.js file for template specific codes.

* Add support of URL (sync)

issue #42

- Perform http GET request and retrieve url body.
- Asynchronous http (module sync-request) with caching, gzip
- Redirection not allowed.

NB: Future optimization could be to provide async operation for the
plugin.

* Update readme

* Update readme

* Remove immutable.js

- Remove immutable package
- Remove Map object to use frozen Object instead (guaranty unmodified
  default map object).
- Update tests.

* Remove parser feature

- Remove URL parser source code (different branch + need update async)
- Remove URL parser test
- Remove package.json dependencies

* Add Eslint config #39 + fix coding style

See issue #39

- Use this convention https://github.com/textlint/textlint/blob/master/.eslintrc.js
- Change Error to Warn for unused vars and allow console logs.
- Add new package script : check => run eslint for javascript files in src/ and test/.
  (Do not add test/fixtures, test/patterns, ...).
- Add travis eslint check.

* add eslint config

* Update reviewed code
