0.9.5.1 bugfix release + a new subroutine

there was a nasty bug involving Endless Mode games, where upon loading an Endless Mode game, the game would probably crash on a later level. this had to do with the minimap... the game was mistakenly giving new planets the same ID as a previous one, causing it to re-use an old minimap... which in turn would crash things, since the minimaps were probably different sizes.

I tried to find a fix to preserve old Endless Mode saves, but couldn't quite figure it out. sorry about that :|

some good news: I happened to have started work on new content, so that's getting wrapped up in this update as well. here's the full changelog:

0.9.5.1

Fixes

• Fixed a bug where loading an Endless save game would probably result in a crash when visiting a later planet. (It's weird. Don't ask.)

Subroutines

• New subroutine: Black Mushroom.

Weapons

• Trail Guns can no longer have EMP bullets.

Armors

• The movement speed penalty and push resistance bonus of Heavy Armors has been reduced from 20% to 15%.

Shops

• The Ophiuchustians no longer have more than one star chart for sale at a time. Because finding a shop half-full of star charts is REAL ANNOYING.
• Ship parts sold in shops now have a greater chance of being "blessed".
