Update tags for Julia 1.0; fix #3

Add support for arbitrarily many macros before functions.
Add variables defined on the start of a line (also has macro support).
Add support for type parameterized inline function, that is
`f(x::T) where {T} = [...]`.
Remove dollar symbols; I don't know their meaning as I haven't used
Julia before 1.0.
Remove `typealias` keyword; does not exist in Julia 1.0.

Problems:
   - Still could use cleanup to not assign the 'function' kind to
     `struct`s, for example.
   - If any matched identifier is between strings or comments, it will
     _not_ be ignored.
   - Lambda functions are added as variables.
   - Functions in the non-global scope are also added. May be desired.
