- General
Add a simple remote execution mechanism.
Initially requires a shared folder (with the remote system where the recording is to be done).
Simply drops a file into the share containing the parameters of the request.
A batch file running in a loop can then easily find the file and get a local DABDig to action it.

Also added an "All" function for multi-device installations - example from requestor was to record the same channel from both DAB and Digital TV - i.e. belt and braces solution.
One day ... should be extended to "Any" and then let DABDig pick the one that appears to be free (and has highest priority).
