TEXT is not escaped

[terijaki]

I've noticed that TEXT data is not escaped.

This is causing particular problems with location when filled with a comma value. Calendars will only take the string up to the comma.
e.g. LOCATION:Alt-Moabit 140, 10557 Berlin, Germany will result in the calendar showing only Alt-Moabit 140

One simple solution would be to escape these characters when they do not have a leading slash: .replace(/([^\\])([\\,\n;\r])/g, "$1\\$2")
