Title: Remove wxversion import errors. Closes #885.

It seems silly to me to have wxversion as a hard dependency when it's not a requirement for a proper installation of wx. Especially so since backend_wx.py still checks the `VERSION_STRING` after using going through all the hoops with wxversion. This is simply an alternative.
