Opening a project by command line

[oxmon-2500]

If someone works repeatedly on a set of projects it would be nice to open the project by command line parameter like:
qucs [ projectPath_prj [ schematicName.sch ] ]
Calling qucs without command line parameteres should works as previously (open the project specified in "Qucs Home")

Command line enhancement: It is now possible to specify a project and schematic files to open by command line.
Usage:
~/local/qucs/bin/qucs --help
Usage: /home/gAz_/local/qucs/bin/qucs [-h|--help] [-v|--version]
qucs -n -i FILENAME -o FILENAME
qucs -p -i FILENAME -o FILENAME.[pdf|png|svg|eps]
qucs [ projectPath] [ filePath1 [ filePath2 ... ] ] ]

-h, --help display this help and exit
-v, --version display version information and exit
-n, --netlist convert Qucs schematic into netlist
-p, --print print Qucs schematic to file (eps needs inkscape)
--page [A4|A3|B4|B5] set print page size (default A4)
--dpi NUMBER set dpi value (default 96)
--color [RGB|RGB] set color mode (default RGB)
--orin [portrait|landscape] set orientation (default portrait)
-i FILENAME use file as input schematic
-o FILENAME use file as output netlist
-icons create component icons under ./bitmaps_generated
-doc dump data for documentation:

• file with of categories: categories.txt
• one directory per category (e.g. ./lumped components/)

• CSV file with component data ([comp#]_data.csv)
• CSV file with component properties. ([comp#]_props.csv)
  -a plugin load (attach) plugin -- under construction -q, --quit exit

Examples:
qucs -n -i schematic.sch -o netlist.net
qucs -p -i schematic.sch -o output.png --page A4 --dpi 120 --orin landscape
qucs -icons
qucs -doc
qucs ../qucs-test/testsuite/AC_bandpass_prj/ bandpass.sch opa227.sch
qucs ~/proj/qucs-test/testsuite/DC_AC_gain_prj "*.sch"

what is the difference between a "project" and a directory?

i suggest to use a letter option for this, like-C project_path. then e.g. in bash, qucs -C project_path [..] should behave like (cd project_path; qucs [..]), but no need for bash.
