• define new shared color - "link" for both UIColor and Color.
• set default color (UIColor.Signal.link) for links in LinkingTextView.
• do not set "UIColor.clear" as underline color for links. just omitting underline style does the job.
• bring back keyboard frame tracking to OWSViewController if running on iOS 15.
• add our own layout guide to OWSViewController that is updated based on keyboard frame notifications on iOS 15; on newer iOS versions it's a proxy to view.keyboardLayoutGuide.
• use OWSViewController.keyboardLayoutGuide where needed.
• in media composer screen (not OWSVIewController subclass) we already track keyboard frame - use that to position bottom toolbar on iOS 15.
I have also discovered that profile avatar editing screen was somewhat broken on older (15, 16) iOS versions. Fixed that here.
revious color was semi-opaque black which meant the resulting color of a selected UITableViewCell's background was not something referenced in the code. Therefore it wasn't easily possible to re-use the color for non-UITableViewCell elements (e.g. creating UIButton whose colors should match UITableView's colors). With the opaque colors final color of the background of a selected cell is known and can be referenced directly.
Also removed Theme.tableCell2MultiSelectedBackgroundColor - use one color for both "single" and "multiple" selection modes.
Fix Calls tab not setting UITableViewCell properly to use custom cell background color in multi-select mode.
Also convert OWSTableContents, OWSTableSection and OWSTableItem to Swift.
The only subclass of OWSTableViewController was DebugUITableViewController which has to be converted to Swift as well.
I also changed OWSTableViewController to be a subclass of OWSViewController (more modern and all in Swift) instead of OWSViewControllerObjc.
