Some events don't propagate correctly to the right sub-window
and some things like the pad handler don't even necessarily have
windows. So, just register some events with the top-level app.
Also add a virtual destructor to the PadHandlerBase to be able to
deal with multiple inheritance in the derived classes.
- Use Bind instead of connect. It's recommended for anyone using wx 2.9+
- Remove AppConnector. All this did was destroy objects used in the UI. However, wxWidgets handles this. So it's redundant.
- Misc other unimportant changes.
*Improved Keyboard:
- Fixed crash when using Null keyboard handler
- Added support for meta keys
- Added support for {caps, num, scroll} lock.
*Small issues fixed in previous module:
- cellGifDec: Fixed wrong information of packet field in
cellGifDecReadHeader.
- cellGifDec: Set DataOutInfo.recordType as 1 since the output is always
an image.
- cellJpgDec: Set colorSpace as 3, until a better function is
implemented.
- cellJpgDec, cellPngDec: Added RGBA support.
*Changed layout of "Config > Settings" menu.
* Implemented 'cellKb*' functions from 'sys_io' module, which are part
of the libkb library.
* Added corresponding entries in the 'Config > Settings' menu to change
the handler of the keyboard. Supported handlers: Windows, Null.
INFO: This keyboard library is *very* experimental and I am aware of
some bugs. There will be improvements soon.
