- minor GUI improvements
Comments
- currently snap daemon (2.40) automatically upgrades your installed applications in background. Although it's possible to check for new updates
programmatically, it requires root access and would mess up with the user experience if every 5 minutes the application asked for the password. But not to let the
user with empty hands, it was added a "Refresh" option when right-clicking an installed snap application. It will update the application if its not already updated by the daemon.

Improvements
- Console output now is optional and not shown by default
- Search bar is cleaned when 'Refresh' is clicked
- Full Flatpak database is not loaded during initialization: speeds up the process and reduces memory usage
- Applications data not available offline are now retrieved from Flathub API on demand and cached in memory and disk (only installed)
- In-memory cached data have an expiration time and are cleaned overtime to reduce memory usage
- Code was refactored to support other types of packaging in the future (e.g: snap)
- flatpak is not a requirement anymore
- the amount of columns of the applications table was reduced to improve the user experience
- new environment variables and arguments: FPAKMAN_ICON_EXPIRATION (--icon-exp), FPAKMAN_DISK_CACHE (--disk-cache)
- minor GUI improvements

Fixes:
- flatpak 1.0.X: search is now retrieving the application name
- app crashes when there is no internet connection while initializing, downgrading or retrieving app history
