level selection and other ideas

[littbarski]

Hello, as mentioned in the other NeoLemmix topic today:

Thank you very much, I really enjoy playing your SuperLemmix!

If you will consider new ideas:
- add an option to disable the advanced options (at the right) of the level selection screen just like in NeoLemmix (or can I add a row in the settings file for that?)
- add font and symbol size option for the level selection (as discussed)
- allow different cursors in menu (I actually took the files from the normal playing cursor also for the menu...)
- perhaps: allow disabling the level countdown timer / counting up, but only an option, I like both ideas.

Some of the ideas are also because we play this in family with kids.
