#214438: convert '\' to '/'

Can anyone review and approve:

http://netbeans.org/bugzilla/show_bug.cgi?id=214438

Justification: Needed for those who install on Unix and try to run on Windows 
or vice-versa. 

Change consists of two sets:
http://hg.netbeans.org/releases/rev/0ba965b4027e
http://hg.netbeans.org/releases/rev/6495f8932dc4

Risks: The first one broke core-main tests. That is good as we know the test 
coverage is good and that the second fix got everything to normal. Right?


Thanks.
