I've implemented it, please review:


I have included the necessary changes to the framework, as there are few.

As both charge alerts are the same now I could also factor out the text 
preparation, saving some ROM space. I intend to reuse the other command 
functions as well, if the parameters can use the same syntax I can just 
switch the argument separator char.
