* The exchange dialog can be now called from the footprint popup menu.
* It can be (as before) called from the footprint properties menu, but in this case, the footprint properties menu is closed before calling the exchange menu.
* Changes in exchange dialog to avoid truncation of long FPIDs
* Changes in exchange dialog to make some texts translatable (Previously, the same English sentence was used in very different contexts)
* Replace module nomenclature with footprint for improved consistency.
* Replace abbreviations in control text.
* Replace exchange nomenclature with change.
Fix also an issue on Windows, when using the footprint viewer or the component viewer in modal mode:
Reason: these frames (when run under the Kicad manager) have the Kicad manager as parent, and were built with wxFRAME_FLOAT_ON_PARENT style.
On windows, when the frame with style wxFRAME_FLOAT_ON_PARENT is displayed its parent frame is brought to the foreground, on the top of the calling frame.
and stays displayed when closing the frame in modal mode.
This issue does not happen on unix so we use now wxSTAY_ON_TOP on Windows, and wxFRAME_FLOAT_ON_PARENT on unix to simulate a dialog called by ShowModal.
This is not perfect, but at least it works.
