* Add CMake script to generate DSN token header and source file from
token list file.
* Add preliminary component library DSN token list and lexer file to
test script and prepare for new component library file lexer.
* EESchema: right click on ERC check mark displays error in message panel.
* Remove PCBNew header file dependency from common DSN lexer source.
* Minor code clean ups.
* 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.
