Previously we would abort, which makes TextMate show an error sheet.

Closes #26.
Let Insert Entity… show entities sorted

Avoid (some) exceptions when inserting swf files via drag’n’drop

Fixes #1.
Use version 1.8 of ruby for bundle items

#ignore

Without this, ‘col’ would match ‘colgroup’ causing wrong indent for the latter.
Allow invalid `<` match to work in all HTML based grammars

Using R: in front of the scope ensures that it loads after any other injected rules to prevent conflicts.
Localize paired quotes for german.
Typing pairs localized.
Make 'Insert close tag' re-indent the close tag.
