#82 Custom EXE fails with special chars in the wrapper's path

[Syao]

== Steps to reproduce: ==

- Create a wrapper with special chars in its path (for a 100% reproducible issue, just use a [string in square brackets] wherever in the wrapper's name or in its parent folders)
- Create a Custom EXE launcher pointing to your favorite windows executable within the wrapper (i.e. /Windows/notepad.exe)
- Launch the Custom EXE

== Expected results: ==
- The custom exe launcher should launch whatever executable you set

== Actual results: ==
- Nothing happens. An unhandled exception is thrown, as shown in the Console log:

2012-04-10 3:58:29.282 am Wineskin: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSCFString substringToIndex:]: Range or index out of bounds'

)

== Issue analysis: ==
After an analysis, the cause has been traced down to the following line in CustomEXE:

CEXENAME="${CEXENAME#${CEXENAME%/*}/}

When special characters are contained in the wrapper's path, the search string on the right side of the hash sign contains special characters, which are handled as such by the shell.

The solution I suggest involves using the 'basename' utility rather than the shell's string manipulation routines. See the attached patch.

Made the CustomEXE launcher more resilient to special characters in the wrapper name

even though i use "git patch" it still sticks my name on it since I'm the only one with write access... but I didn't modify your patch any.
