Robin Gareus 1d2a76f239 Free some one time alloc of the UI (cleaner valgrind output)
No incremental leaks here..
* downcase (const char*) uses strdup, caller needs to free
* free allocated cursors when the editor is destroyed
* drop static editor lua-instance & bindings
* delete allocated gtk image/icons
