[trojita] Open composer window with arguments

[Dimitrios Glentadakis]

Hi, i'd like to ask if it is supported to open the composer window with 
arguments

I found this discussion but did'nt give me any hint.

I run trojita in a lxqt desktop and when i click on a link with 'mailto:' 
it opens just trojita's main window (a new one)
