We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Rather than displaying the path of the framebuffer, try and display
the manufacturer name and the size of the display. If no EDID data is
available, fall back to showing the device path.
This is functionally the same as before, as selecting a tab fires Show
and HideEvents. But this way, we don't need to directly access the
TabWidget, which will make using SettingsWindow simpler.
This enables changing monitor settings for each monitor individually.
In the event that changing a resolution causes screens to overlap we
now try to disperse the screens, although the algorithm currently
implemented may result in some rather unexpected layouts in certain
cases. We can still improve this logic, and eventually we're going to
have a widget where the screens can be arranged as desired.
This sets the stage so that DisplaySettings can configure the screen
layout and set various screen resolutions in one go. It also allows
for an easy "atomic" revert of the previous settings.
