Changes to mod settings UI

[originalfoo]

Poor choice of words on some options/headings in mod settings is causing crufty workarounds in the documentation. I've done mockups of suggested changes below. New locale strings should be used to encourage translators to update translations.

The changes should wait until after #51 (toolbar --> build bar) is complete, as that makes some options obsolete and others are moved to the build bars.

• General tab: See Reorganise mod settings - General tab? #1262 & Refactor OptionsGeneralTab.cs #1267

Forgot to mention here but it would also be very useful to allow global settings (from main menu) to be defined and used as defaults in any new games. (Steam user "Action Jackson" just mentioned this on Stable workshop page).
