Adding extra 3.0 features

[glenrobson]

Added:

• Up scaling
• Removed size full and replaced with max

So to fix the travis checks it looks like I have to deploy a new version of the iiif-validator to pip

[glenrobson]

Now need to fix the formatting errors:

 '\n\n'

iiif/manipulator.py:310:13: E201 whitespace after '('

iiif/manipulator.py:310:16: E225 missing whitespace around operator

iiif/manipulator.py:310:32: E225 missing whitespace around operator

iiif/manipulator.py:311:15: E111 indentation is not a multiple of four

iiif/manipulator.py:311:39: E231 missing whitespace after ','

iiif/manipulator.py:312:22: E128 continuation line under-indented for visual indent

iiif/request.py:420:68: W291 trailing whitespace

iiif/request.py:423:38: W291 trailing whitespace

The command "pep8 --ignore=E501 *.py iiif/*.py iiif/generators/*.py tests/*.py tests/testlib/*.py" exited with 1.

Coverage decreased (-0.4%) to 97.711% when pulling b05f79213c0a31f2a65466a8d2b60012d387a8ef on glenrobson:version3 into bc82930a92025a4ae4b1509748269d239ab59741 on zimeon:version3.

I think this is ready for merging if your OK with it.
