Allow configuration of different action ids

[behrica]

I found our plugin very useful to generate a nice keymap for intellij.

I had the need to extend it to allow other action ids to be shown in the PDF.

I just did that "hard-coded" so far, and I was wondering if you have some plans to allow the dynamic addition of action ids in some point in time.

I saw, that is has already the concept of action profiles, but even with those the action id's are still hard-coded. To allow the action ids which are contributed by other plugins to be shown, this is neither sufficient.

Maybe you want to have a look, what I did and let me know, if you have any plans to develop this plugin further.

I completed as well the build script to generate the full plugin zip from command line.
