Plugins are going to need to be updated.
The two main points are:
1. DrPython wx events. (Which should not be a huge issue, as I do not think this has been used as yet)
2. The new code for adding a panel.
There is now one necessary additional step, a new function name for getting the target panel and index,
and an additional optional step to ease having a particular default panel size other than that set by default in the preferences.
(I also need to adjust the font sizes for the about dialog on windows.)
