Tooltip

[Toma400]

Tooltips are great way to show stuff that needs some contextual help. It will be quite powerful thing in later development phase, but even currently it will be very useful, for example:

• to show how left/right/middle mouse clicking works in settings
• to show stuff that is contextual in loading/saving/gameplay options which nowadays use PyGameGUI textboxes

Current form should use primitive one-line text system, but later should be replaced with Text, since multilined text system will be way more powerful and useful.
