Patch #17654: Fix for Scene.Get with input >20 chars
Patch by Darryl Pogue (paradox).

Blender cuts off datablock names at 20 chars, which causes issues if you're trying to access Scenes with a string longer
than 20 chars.

Ex.

s = 'GuildPub-Writers_GLOBAL'
Blender.Scene.New(s) #This creates the scene "GuildPub-Writers_GLOB"
Blender.Scene.Get(s) #This throws an error: the name and the string don't match

This patch cuts down the input of Scene.Get() to the 20 char limits, thus making the the above example return the correct
scene.
