Feature request: Integrate batch mode

[Reissner]

First of all, batch mode is quite important for me as creation of .h/.c is part of build process. What is bad is, that currently, there are two applications: EDSEditor (GUI) and EDSSharp (Batch). I would prefer to have a single application, best called EDSEditor. This would solve also the problem that the results are not the same in the two applications.

Suggestions:

• add an option --GUI or maybe --no-gui to determine whether a gui raises or not.
• The option --infile shall be possible also in conjunction with GUI because, it is faster when launching EDSeditor from command line.
• I dont know whether option --type CanOpenNode is really necessary. It seems to refer to the output file format and edseditor seems to be restricted to that format. In this case, it seems appropriate to restrict that option to --no-gui.
• or course, --outfile shall be restricted to batch mode, i.e. with --no-gui.
