Fixes and improvements of some names displaying.

[VladiStep]

Description

1. Fixed displaying of a title of the tab with multiline UndertaleString - only first line will be displayed.
2. Added 64 character limit for tab titles.
3. Optimized displaying of UndertaleString names in the "Strings" list - added 256 character limit; newline characters are replaced with spaces.
4. Fixed "glitchy" scrolling of the list, with non-empty search box.

Closes #953

Caveats

A object name of a tab may not be fully displayed - not everyone may like it.

Code review coming soon too.

• Your check to get rid of newlines doesn't seem to work, as they're (sometimes) still displayed. Personally I prefer this, and think that getting rid of newlines would make this section a lot less readable. The ... is good enough IMO at showing that this is a shader and not fully displayed.
• Strings with multiline still screw up the title bar.
  

I was still getting lag when scrolling via scroll bar (not scroll wheel), and don't have previous behaviour in mind right now, but it doesn't feel as if there is less lag than on master.

Could you check what newline character these strings use? \n or \r\n ?

[Miepee]

They seem to be \r\n

Yeah, ngl the newlines being replaced looks very weird in cases like these:

It did fully fix the lag tho, and the other solutions aren't really much better either sooo ¯_(ツ)_/¯
