Suggestion: Allow setting current directory and command line

[CherryDT]

I cannot attach this to the Daedalus wallet because it needs to run from a specific current directory. It would be great if there were a way to set the current directory (and maybe also command line, may be needed for some things). Also, the default for current directory should probably not be %localappdata%\Debugtron\app-0.5.0 but the directory in which the debuggee executable is located.
