The patch implements a small change when clicking on a hyperlink.
Mindmanager only supported URLs (http, file, etc.) and file paths, while browsers and OSes can be expanded to support further protocols.
A frequent request is e.g. to support hyperlinks to Lotus Notes via the notes://... protocol.
With the change mindmanager now supports arbitrary URIs, i.e. any protocol which is offered by the OS is now also available within mindmanager.
The same mechanism can be used to pass parameters to tools (also an existing request), since the URI is passed to the protocol handler and can contain parameter information like known from web pages (e.g. myprot://arg1?arg2?arg3 or alike. The protocol handler can parse the string arg1?arg2?arg3)
