* Replaced find dialog with wxFormBuilder version.
* New find dialog is modeless, supports more advanced search features,
remembers it's last position, size, search history, and search settings,
and implements initial support for replacing.
* Added Shift+F5 hot key to search for next DRC marker. F5 now just
repeats previous search.
* Minor cosmetic enhancements to label edit dialog.
* Remove tab from grid size text printf to fix toolbar grid combobox
display in wxGTK.
* Updated my TODO list items.
* fixed a bug in hierarchal shematics where a loop (e.g. same file included at different points in the
hierarchy) would cause infinite memory use.
* added a edit footprint hotkey to eeschema, since it seems I'm always editing '0603' '0402' etc. on the
common components, and it was difficult to edit this information before.
