GTK: set the mouse cursor on the Scintilla view to signal business and on the popup entries
* By default, use the "text" cursor - this is the default Scintilla cursor, but
inhibited by the GtkEventBox I used to catch all input events.
* When processing input events, the cursor is changed to "wait".
This is done with a small delay in order to avoid flickering during normal typing.
The cursor is only changed after 100ms of activity, i.e. only when executing long loops
or external programs.
* We use the raw GSource API since it's tricky to work with source ids if the
source could be removed in the meantime.
* The popup entries' cursor is also changed to "pointer" (hand) to give a hint that
it can be clicked.
