Ensure that wxFileName::GetTempDir() doesn't return trailing slashes.

Browse Source 
Sanitize the value returned by GetTempDir() to ensure that it doesn't have any
trailing path separators. This happened at least under OS X where standard
TMPDIR has a trailing slash and was inconsistent with the behaviour under the
other platforms.
