Bug: Groups containing a single quote (') in the name fail to collapse

[cnapolit]

If a group name happens to contain a single quote (i.e. "Beat 'em up"), It is unable to collapse. Removing any reference of the quote fixes the issue.

My guess is this name produces invalid syntax when invoking the ShowHide method:
ShowHide('Beat 'em up')
Leading to text that does not correlate to variables, keywords, or functions, and an incomplete string.

Have only tested on the default page view. Unknown if any others are affected.
