Discord-like Quick Switcher (#1588)

* Proof of Concept for Quick Switcher * Fix crash when suggestions are empty * QuickSwitcher: Use tab name instead of a single channel * Rebase later * Add missing include for <functional> * Move QuickSwitcher related classes into own subfolder * Refactor switcher list items Now, items are responsible for taking the right action when selected in the switcher list. This should allow for more focused code and responsibilities. * Add note about memory management * Add option to open channel in a new tab * Add support for using the mouse * Spawn switcher popup in the middle of the window Works reliably on i3 at least. Might need some additional testing on other WMs (and especially on Windows!). * Add some icons for switcher items Note that the final design of the list is not final but I do plan to incorporate these in the future. * Set Qt::Dialog window flag on switcher popup Prevents tiling window managers like i3 from trying to tile the window. * Rename "SwitcherItem" to "AbstractSwitcherItem" * Add comments about what items are inserted * Use custom model and view Still missing: Currently selected item is not highlighted yet. You can move between selected items with tab and arrow keys though. * Add helper function to convert QVariant to AbstractSwitcherItem * * Remove useless constant * Highlight currently selected switcher item * Use a different method for centering QuickSwitcherPopup window * QuickSwitcherModel: Add documentation * Add default parameter to QuickSwitcherModel::rowCount * QuickSwitcherPopup: Add comments * Remove outdated TODO * QuickSwitcherModel: Init vector with default capacity * Remove outdated comment * Add comment about 0 ms timeout interval * NewTabItem: Simplify interface * Only fetch opened splits once This is better than the prior approach since opened splits cannot change anyways while the switcher is open. * Use SplitContainer to pass information instead of custom type * Allow searching for tab titles as well Before this commit, only channel names could be searched. * Refactor switcher item interface to be more flexible Also show tab name and channel name in the switcher list. * Add documentation for AbstractSwitcherItem * Add documentation for NewTabItem * Add comments about {begin,end}{Insert,Remove}Rows * Remove unused method * Replace magic size with named constant * Add change log entry Co-authored-by: fourtf <tf.four@gmail.com>
