Add export profiles

[CePeU]

I am currently looking into how to make an easy build process for publishing my obsidian notes to github (so you will get 3 enhancement proposals).

It would be nice if uppon choosing to export the command would open up to the right and offer additional profiles for export.

I am not sure how difficult it would be and one would probably need to make a separate profile section in the configuration.

I imagine something like this:

Export to markdown ---> Profile 1
---> Profile 2
---> Github enhanced
---> etc ...
