Allow changing CodeMirror showCursorWhenSelecting option

[zenwarr]

Why brackets configuration file does not allow to override CodeMirror 'showCursorWhenSelecting' option? I understand this is not a big improvement but cosmetic change, but i prefer how sublime text editor looks after selecting code block and splitting selection into lines. Another point of this change is to help novice user quickly distinguish single continuous selection from set of consecutive selections. Compare:
Brackets:

Sublime Text:

FYI @zenwarr, this will work in Brackets 0.44 (not yet released)

Closing as fixed.
