Subject: Add basic alarm handler for webkit notifications. Doesn't really work yet
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=e202756fcca5d9e6773e20419a48d7c27c5e4151;p=horde.git

Add basic alarm handler for webkit notifications. Doesn't really work yet
because:
- javascript notifications are broken
- permission dialogs are only displayed after onclick events.
