GMS2_RPC Version 2

The changes in this version introduce several quality of life improvements.

---

Changes from Version 1:

Changes to the existing content:
| The "About" window: Updated the link to this repository.
| Rich Presence: Improved the detection of duplicate project titles by making it compare only the project titles instead of the full window title.
| Application files: Renamed the "lib" folder to "libraries".

Additions:
+ Rich Presence: Functionality of toggling the display of project titles. When disabled, the number of currently running projects is displayed instead. This can be performed through the tray icon context menu and is saved in the config.ini file.

Removals:
- Application files: Prevented unnecessary files from being included with the application build.
