Merge pull request #1 from psecio/master

Merge in upstream changes
Added upload_tmp_dir rule
Fixed logic check to not validate against a string with the contents of open_basedir embedded (e.g.: /tmp would validate against /not/in/the/tmp/folder)
Added new post_max_size rule
Added new upload_tmp_dir test (not a security check, but a common issue that will arise when open_basedir is specified as per the recommendation of the ini scanner).
Merge pull request #66 from xsist10/master
