branch on double swing door direction for sim generation

[codebot]

• branch depending on sign of motion_direction for double hinged doors when generating simulation model
• use the motion_degrees parameter when generating double hinged doors
• add a test map package that has a pair of double swing doors (one with positive motion direction, one with negative motion direction) that will crash into vending machines if they open the incorrect direction
• fix an unrelated but annoying bug when trying to move models in the GUI when explicit scale or measurements were not provided

@aaronchongth @Yadunund I tested this against a minimal test case with positive and negative double-hinged doors. Can you verify if this fixes the other problems seen yesterday and today? Thanks!

just checked with varying door types in office world, it works great! Thanks for the quick fix!

Works really well and the previous maps are functioning as expected!
