Fix typos in build scripts (see bug #1305427)

the option -e to echo is useless here

osx-app.sh - added an help message - changed the calling syntax to make it more robust and allow to specify the directory containing python modules - removed the reference to libXinerama on Tiger. libXinerama caused many issues but they seem to be all related to people installing x11 in strange ways - use pkg-config to get pango and gtk version rather thn relying on clucky ls+sed workarounds - code reorganization and added comments - spaces to tabs osx-dmg.sh - removed python related stuff - added a command line option to get Inkscape package (the package does not have to be in the same directory now) osx-build.sh - modified according to the changes in the two other files - removed referece to X11 libraries ad such. these were commented for a while and nothing broke - added an upload commnt to send the file to modevia removed inkscape_python.ds_store modified inkscape.ds_store (larger window) dmg_background.*** - removed Python arrow - remove the word Inkscape from the arrow (useless now) and make this arrow glow green a little, as the rest of the picture - removed absolute paths to my computer

modified the symlink for python packages to point to the real location (inside python framework) instead of /Library/Python/... which is a link to the real location. Indeed the link is broken on 10.3 aka. Panther

-added some checks for the existence of Inkscape.app and a better way to check for the existence of the python modules directory - added some comments hopefully to improve overall readability

modified the way -py option is handled to account for spaces in the PATH and avoid putting extra quotes

- committed patch 1710671 to osx-build.sh from John Faith which allows prior detection of the variable $INSTALLPREFIX in the environment. The other solution would be to supply it as a command line parameter, the code is here but commented at the moment. We should decide which solution is the most pratical - additional file existence checks in osx-build.sh - added checks for success of each step of osx-build before proceeding to the next one (via exit status) - split the PACKAGE action into a new PACKAGE action (creates the app bundle) and a DISTRIB action (creates the dmg image) - added an exit status for osx-app and osx-dmg - removed the old call to osx-dmg at the end of osx-app (it has been commented for a while anyway)
