vfsStream 0.3.2 released

Nearly about a year passed since the last release of vfsStream, and some bugs were found by users of vfsStream. This was quite a surprise for me since I did not expect that anybody would use it.
This evening I fixed another bug reported some days ago, and since a patch for another bug was submitted and committed about half a year ago I decided to release version 0.3.2 tonight, so these are the changes:

- added support for trailing slashes on directories in vfsStream urls, patch provided by Gabriel Birke
- fixed bug #4: vfsstream can only be read once, reported by Christoph Bloemer
- enabled multiple iterations at the same time over the same directory

A big thank you to the bug reporters for their help to improve vfsStream. This should give me some motivation to go for 0.4.0 and implement support for file modes, at least being able to store and read them - full file mode support will be a hell of a work, not sure if it is worth the effort.
