- Fix a bug where clicking the "Add Event" button created an empty title in the event editor dialog.
- Add "error" class when the user writes an invalid event name.
- Add new function to validate event name.
Because the sections are split into files, the event editor will need a signal to check that each section is correct, and each section will have to emit the signal. This will need to be done in a future commit.
We want them to grow a bit more, and not let the expansion
of the title label detemine the width. Allow the location
and title entries to expand, and set a maximum width char
to 30 on them.
