Detailed description

Added the cmdline option to open a file directly in write mode. If an analysis level is selected,the file will be opened directly in cutter without displaying any further settings dialog window.

Test plan (required)

• Check if old functionality still works:
• • Cutter -A 0 TESTFILE Open a file directly without the -w parameter on the commandline. Should open the file directly in cutter and ask to enable write mode if trying to modify.
• Check if the write mode parameter is handled correctly:
  -- - - Cutter -w -A 0 TESTFILE Open a file directly in cutter in write mode without any further confirmation when modifying it.
  -- - - Cutter -w TESTFILE Open the Load Options to ask for further settings for opening TESTFILE in cutter, with the "Load in write mode (-w)" box already selected:

Thank you and welcome!

Fantastic job! Looks very nice and works even after rebasing to master (with the latest changes of IO Mode modification).
And you even added the documentation - sweet!

I left a single comment about grammar, other than that, it's good to be merged :)

Thank you!

Changes in the documentation are fine for me, sorry for the delay and thanks for the great feedback :)
