Second Event editor update

[Johannes-callidus]

This will over time extend to a second event editor rework.
What it currently changes:

• Adds action to change the model data of a house e.g. water, entertainement, eductation ... requirements
• Adds powers to formulas in form of the '^' symbol and makes random values include the max as a possible value
• Refinement for building model window
• Refactoring of some model related functions
• Fixes latrines house evolve texts
• Clamping values for some data types
• New function: text_draw_centered_without_bounds which drwas centered but is not left aligned when it's bigger then box_width but does if it's bigger then window bounds.
• Fix issues with import and export windows offseting some buttons
• Fix a bunch of bugs related to model data notably when setting to value always setting to 0
• Maybe some bugs
• Increases savegame and scenario versions
• And more

whoops I accidentally found the latrines evolution bug myself and submitted my own fix! I'll keep it up just in case but yours probably fixes that and a hundred things more, neat!

Is this ready for review?

[Johannes-callidus]

No, it isn't yet. I'm currently working on copying events and selected conditions and actions. Copying events is already possible but not the selected.
