Boolean settings are not implemented

[jako4295]

None of the boolean settings are implemented yet and therefore do not change anything when toggled in settings.

There needs to be implemented the following functionalities for now:

• [x] capital_letters: include capital letters in the typing test
• [x] numbers: include numbers in the typing test
• [x] parenthesis: include different types of parenthesis in the typing test
• [ ] #27
• [ ] #28
  • [ ] characters per minute

It is not yet decided if including more characters should imply that all possible characters are drawn uniformly, if there should be a higher chance of getting a standard letter, or if this should be an option in the settings. As a first implementation, it should probably be whatever is the simplest to implement

Perhaps add an easter egg if all characters are disabled - maybe something like a pre-determined sentence to type - suggestion: "You thought you could disable all settings and still play? How dumb." Or something else creative.

• [x] If disabling all settings (including lowercase letters) it is no longer possible to launch the game - This could be handled with the suggested Easter egg.

Moved the rest to two new issues. The rest is done
