0.3.0

### Features
- Applications search
- Now when you right-click a selected application you can:
    - retrieve its information
    - retrieve its commit history
    - downgrade
    - install and uninstall it
- "About" window available when right-clicking the tray icon.

### Improvements
- Performance and memory usage
- Adding tooltips to toolbar buttons
- "Update ?" column renamed to "Upgrade ?"
- Management panel title renamed
- Showing runtime apps when no app is available
- Allowing to specify a custom app translation with the environment variable **FPAKMAN_LOCALE**
- Adding expiration time for cached app data. Default to 1 hour. The environment variable **FPAKMAN_CACHE_EXPIRATION** can change this value.
- Now the application accepts arguments related to environment variables as well. Check 'README.md'.
- Minor GUI improvements
- Notifying only new updates
- New icon
- Progress bar
