Name change events for Mazurskie <-> Masuren

Split Masuria from East Prussia so people can make Imperial German borders if they really have to

Removed political change decisions (Fascism on the Rise etc) since there are events to handle this and I haven't had time to fully understand the system (sorry, Gabriel)

Civilian economy and volunteer army now give small bonuses to stability
Gave Sweden a field marshal

AI will be more likely to take ministers with political power bonuses (eg Silent Workhorse) early in the game, and will be more likely to take NFs with political power when at war with bad economic or manpower laws.

German Civil War victor that changed its ideology will now get its "political situation resolved" (so it can change flags) and have the former country leader's national spirit removed

Restored some vanilla events, attache complaints and injured and sick generals should work again
Austria gets news events when forming Greater Germany and her decisions to change country name work more reliably

Altered map to be compatible with 1.5.2 (Silesia etc)
Economy laws now require war support
Added Revolutionary Republic national spirits to Caucasia, Baltic, Ukraine and Belarus, giving bonuses and bypassing war support requirements for economic mobilisation
Changed Ernst Thaelmann's portrait

Fixed problems with a state ID (Rijnland) that was changed in patch 1.5

Updated to 1.5
Added some decisions to change flags
Changed the military ideas to give starting stats as well
