#193 MiddlegenIDENewWizard assumes file separator to be "\\".

[HARUYAMA Seigo]

I use MiddlegenIDE 1.3.3 on Eclipse on GNU/Linux System.
When I launched Middlegen from MiddlegenIDE, I got a
error like
http://ultimania.org/middlegenide/hiki.cgi?Middlegenide%2BHibernate%2BOracle9i
.

I think it's because
org.ultimania.middlegenide.wizards.MiddlegenIDENewWizard
assumes file separator to be "\\".

-----MiddlegenIDENewWizard.java-----
140 IResource projroot =
root.findMember(new Path("\\"+container.ge
tProject().getName()));
