Fix UX: replace "upgrade/install" buttons with checkboxes
The current version of pamac I'm using is 8.0.3-5. I didn't really notice, but it's been awhile since the convenient checkboxes in were gone. Previously, selecting only one of few package for upgrade was easy: deselect everything and selecting what is needed. Now, it's a pain to click "upgrade" buttons on every package.
Common use cases:
- I want to upgrade only binary packages and non from AUR
- I want to upgrade only certain AUR packages
Solutions:
- Return checkboxes (preferred one, because it's standard and more convenient)
- Re-implement "Select All", "Deselect All" item to right-click context menu (which is basically reinventing checkboxes with no obvious benefit)
