Fix orbital scheme's handling of embedded ':' char
Created by: NilSet
Problem: the orbital:
scheme was incorrectly parsing urls that contained an embedded :
. This made the file_manager app crash when it tried to set the window title to a path with the file:
scheme included.
Solution: Split url at the first :
only.
TODOs: Come up with a general way of escaping data passed into schemes?
