Thursday tune-up patch

This is a small bugfix patch that fixes the following issues:

• First game: When using the first game mode, it was possible to trigger a crash by using the "Abandon run" option
• Achievements: The "12-science lab" achievement sometimes prematurely unlocked when the Self-Hosting AI technology was used
• Controls: Modifier keys could get stuck after Alt+Tabbing or Cmd+Tabbing away from Slipways.
• Controls: Pressing some keys during game load could lead to a crash due to user settings not being available yet when the keypress was handled.

In addition, here is a list of quick fixes done between the first update's release and now, mostly in the form of small hotfix patches:

• Crash: Sending a probe and quickly pressing/releasing another mouse button could trigger a crash.
• Crash: Using the "jump to" functionality in the domain tab would sometimes trigger a crash in the UI system
• Crash: The stats window would sometimes crash in Endless mode due to incorrect handling of difficulty level
• Controls: Alt/Ctrl and other modifier keys were unusable on Mac OS
• Tooltips: Using the "sticky help keys" UI setting could prevent tooltips from appearing correctly
• Tooltips: Undo button tooltip included the hotkey information in weird places for some actions.
• Probes: The "send probe" hotkey made it possible to start probing while in a ruin event, confusing the UI system and resulting in a stuck probe.
• Achievements: Some "challenge run" achievements could be unlocked in an invalid way by starting from an old pre-update save that did not track relevant data
• Achievements: In some rare cases starting from a pre-update save, it was possible to unlock an achievement that was not available in this game mode.
• Stats: Stats displayed in the stat window for "forgiving" displayed a "sandbox" difficulty incorrectly

This patch brings the version numbers up to 1.1 (b805) on Windows and 1.1 (b806) on Mac.
