Flags are encoded using internal wx values, that can change with wxWidgets versions.
They need to be always rebuilt from the displayed options in dialog.
From master branch.
Also rewrites the PCBNew Find dialog to make use of the above, including:
1) searching in user-defined footprint fields
2) searching in pcb text
3) a history list in the search popup
4) case sensitive searching
5) word sensitive searching
6) the ability to turn wildcard searching on/off
7) better placement of the result when the dialog obscures part of the
window
