Release 0.6

[Stéfan van der Walt]

Hi everyone,

It's time for another release of scikits-image!  I would very much
appreciate your help in reviewing the following outstanding
pull-requests:


- Tony Yu's neat visualization tools, previously packaged as skloupe:

https://github.com/scikits-image/scikits-image/pull/165

- Fast image warping:

https://github.com/scikits-image/scikits-image/pull/184

- RegionProps (still awaiting tests, but review the rest so long)

https://github.com/scikits-image/scikits-image/pull/183


This release is due in about 10 days.  I'm also happy to report that
our Debian package has been submitted for approval; thanks go to
Yaroslav Halchenko!

Stéfan
