Bug: [#17734] Loading a python script's help dosn't work reported by Rian Tut (thanks). Actual problem: scripts with spaces in their filenames were not supported by the code that registers scripts in menus and runs them. Added support w/o breaking eventual, rare scripts that parse the Bpymenus file. They will still need an update to support filenames with spaces, like done here for these scripts: Scripts Help Browser and Scripts Config Editor. PS: tested on Linux. Please test on other platforms: just make sure scripts still appear in menus (the File->Export, for example), even after re-registering them (Scripts window -> Scripts Menu -> Update Menus) and that the Scripts Help Browser still works.
