"Make Me Admin Remote" for multiple targets

[kheldorn]

In addition to the request in #142 there is often the requirement to do administrative tasks against a greater number of computers. This can be 5, 20 or even over 100 at once.

Tasks vary from killing processes so an update can be installed, mass-deleting temp files or just querying information from remote machines.

Currently it would be very labor-intensive to even request remote admin permissions on 5 computers.

Thus I'd like to suggest a feature that allows requesting admin permissions on multiple targets at once.

It could be solved by accepting a comma-separated list of host names into the input field, splitting the string up at each comma, truncating each host name and then sending a request to each host name. Alternatively a bigger list-type input field you be used where host names are entered one per line.

This should definitely be combined with #67 so you actually get a meaningful feedback on which computers the request worked and on which it didn't.

Additionally this should work with the feature requested in #145 to request longer durations of admin permissions on remote machines.
