Add ResultAppleEventCode to launch session

Fixes these console warnings:

scriptSuite warning for result type of command 'launch' in suite
'iTerm': the type PTYSession ('Pssn') doesn't match the result Apple
event code ('').

Cocoa scripting error for '(null)': four character codes must be four
characters long.
Fix redraw-bug in split-panes on Retina displays.

The check for resized frame sometimes failed when a horisontal split
-pane is in use, since it might have non-integer height due to
fractional pixels - possibly only in scaled resolutions.
Rework how character runs are done. Big clean up.
Support non-modern runtime for latest changes. Fix a bug where there are no glyphs.
