Allow apostrophes in custom button names

[mzazrivec]

1. create a custom button with a dialog, name it so that it contains an apostrophe in its name, such as: Button l'Muf
2. click on the custom button (in the place where the custom button shows)

Without this fix, the following javascript error would show:
