Also updates the file menu IDs so that we can actually handle
more than 9 items in the file history.
Also adds configurable file history length to the other gerber
files (zip, drill and job).

Primary change is to replace most control/window borders with
AUI pane borders. We implement our own AUI border drawing
routine which avoids the ugly one-pixel white frames around
dark canvasses.
Also increases the signal-to-noise ratio of all the pane
creation code in the various frames.
This allows it to participate in Kiway things such as updating
language or common settings.

(cherry picked from commit b3f8478)
KiCad read incorrect value for window position and it's size at very
first launch, which results in invisble/inaccessible window on Mac OSX.
Set correct default values for these settings fixes this issue.
And fix a typo in comment.
