The indent size was estimated by the width of characters. But MSW
indent is substantially different from OSX and Linux. It also cuts off
the middle characters rather than the end leading to poor display if the
width does not fit. This uses the system setting for indent to account
for the indent spacing + 'M' to account for the arrow inset.

When filtering, we update the width of the displayed column to ensure
the full text is visible to the user. Check is rough, based on line
width (doesn't completely account for differing char widths) but is
sufficient for the approximate difference

When the user cancels the footprint load, we should assume they are
canceling the placement of a new footprint. This also adds sanity check
when populating the list

Be more intelligent about sorting lib tree items. (Footprint
entries, for instance, come out of an already-sorted list.)
Don't recreate menus twice when laoding Footprint Editor.
More pervasive use of WX_FILENAME to avoid expensive calls to
wxFileName::SplitPath() and string concatenation.
For POSIX kernels do all the work on the file-system side so we
don't have to keep converting back and forth between encodings.
