Show full master preset name in BTT config window

Right now BTT truncates the name of your master preset, making GC’s preset name appear just a single character short of the full name (GoldenChaos-BTT 3.36 vs GoldenChaos-BTT 3.368). This can make it difficult to know what version of GC you’re running at a glance.

However, it would be great if the field would only truncate the name if there isn’t enough room. Additionally, when it does truncate, please use an ellipsis (...) to indicate that the name of the preset has been truncated!
