Release v0.0.5 (#18)

* Update README.md to reflect version bump

* Update to README.md, new shields

Added AUR Package shield
Changed gitter.im shield

* Added support for oblique gesture swipes.

To add the support the config class was modified to include the new
gestures types: left_up, right_up, left_down, right_down.
Also changed the way the commands are saved in the config class, so
there won't be a need for a lot of if statements to handle 4 finger
swipes and 3 finger swipes.
Finally, the handle_swipe_event_without_coords was modified to detect
the oblique swipes.

* Commenting the code a bit and some minor cosmetic and semantic changes

- Added comments to each function
- Increased string array size to 10 in config.h even though we only need 9 slots, I'm being a bit pedantic about this
- Adding some build flags to CMakeLists.txt to show every error, preferably we'd get clean output eventually
- Renamed find_gesture_device to gesture_device_exists in Input class
- Renamed find_config_file to config_file_exists as this actually describes the logic of this function in Config class
- Renamed find_home_folder to find_config_file in Config class in preparation to adding /etc/gebaar/gebaard.toml to list of possible config file locations

* Prepare for release by bumping up version in README.md

* Let warnings be warnings, release v0.0.4

* Goodbye Gitter, Hello Discord.

* Fix config location (#13)

If XDG_CONFIG_HOME is set, .config will be appended a second time
resulting in /home/example/.config/.config/gebaar/gebaard.toml

This is fixed by only appending .config, when the HOME directory
workaround is used.

Fixes #12

* Fix nullptr conversion to std::string (#16)

Instead of using the result of getenv directly, we must check first, if
getenv returned a nullptr, otherwise the program will crash.

Regression from 41c7c05

* Add the build directory to gitignore (#15)

The README build instructions use this directory.

* Add a desktop file (#14)

Users can copy this desktop file to $XDG_CONFIG_HOME/autostart to enable
autostart on most desktop environments.

 Gebaar directly interfaces with libinput to receive and react to the events.   
 This is more stable, faster, and more efficient as it **does not parse the output of a program** like the aforementioned projects do.
