graphics/opencolorio: 1.0.8 -> 1.0.9

- Updating to a557a85454 on the master branch.
  This is the 1.0.9 release plus some fixes needed to resolve
  some build issues.
- Updating slave port graphics/opencolorio-tools
- Adding new slave port graphics/py-opencolorio to allow concurrent
  python module installs. Python 2.7 and 3.3+ is supported. py3.2 fails
- graphics/opencolorio uses python2 to generate documentation, using
  python3 fails to find the python module in the build dir, as this
  only relates to generating the docs we can limit the master port
  to py2.7 while there is no issue with py-opencolorio using python
  2.7 or 3.3+

Fix opencolorio-tools build. Now that opencolorio has a post-patch,
opencolorio-tools can't have one.

opencolorio-tools fails stage-qa, though, due to some stray files
in STAGEDIR that are probably simplest to just list as @comment inside
pkg-plist-tools:

===> Checking for items in STAGEDIR missing from pkg-plist

Add NO_STAGE all over the place in preparation for the staging support (cat:
graphics)

Add new port graphics/opencolorio-tools.

This is a slave port of graphics/opencolorio containing the utility
applications of graphics/opencolorio (former CLIAPPS option on
graphics/opencolorio).
