[OS X] launch Inkscape with a login shell

[su_v]

The Inkscape.app launch script inherits the minimal shell environment of launchd. Current system and user configuration files are not read.

Proposals:

1) bash sh-bang with --login option in script and openDoc (diff attached)

from the bash reference manual:
"When Bash is invoked as (...) a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable."

Changing the sh-bang line of Resources/script and Resources/openDoc to
 #!/bin/bash --login
gets the current system (x11, macports, fink) and user (local) environment to inkscape.

Additional PATH settings in Resources/bin/inkscape then can be reduced to specially needed Frameworks(?).

Caveat:
Empirical testing - I don't have C/C++ coding skills - showed that this does not work when the LauncherApp/ScriptExec uses NSTask (Platypus 4.2), but works with execve() (inkscape/packaging/macosx/ScriptExec/main.c in ExecuteScript()).

2) bash login shell wrapper added to current ScriptExec

If the bash login shell implemented as sh-bang doesn't work e.g. for older platforms (Tiger, PPC?), maybe adding an explicit interpreter with --login argument to execve() in ScriptExec/main.c is more portable? This is similar to the way MacVim starts vim with a login shell.

Other applications that use a (bash) login shell:
  X11.app <http://cgit.freedesktop.org/xorg/xserver/tree/hw/xquartz/bundle/X11.sh>
  MacVim <http://repo.or.cz/w/MacVim.git?a=blob;f=src/MacVim/MMAppController.m> (line 2001-2102)

3) new ScriptExec based on Platypus 4.2

Platypus 4.2 <http://www.sveinbjorn.org/platypus> offers (gui) configuration of interpreter+arguments+script+path of a launcherApp; implemented as NSTask. The code for the ScriptExec binary has been rewritten in Objective-C and Cocoa, implementation of openDoc/Drag&Drop changed. Interpreter+arguments can now be configured/changed with Resources/AppSettings.plist without recompiling ScriptExec.

Inkscape specific fc-cache and X11 related functions in ScriptExec would have to be rewritten. Resources/script stays unchanged or could be combined with openDoc and bin/inkscape.
