setup should not require ExtractUrlPlugin

[walther@…]

In setup.py the directive setup_requires = ['TracExtractUrl>=0.2.7030'] is set making egg building impossible on "non trac" machines.

Without it ./setup.py bdist_egg will run fine, also installation at the target system with installed TracExtractUrl.

So if there's no other reason I'm not aware of enforcing setup_requires, please drop it.

Yeah, setup_requires doesn't seem to be needed. See ​setuptools documentation for more info. See also #6940.

We are planning to use this plugin on trac-hacks, so I hope it is okay with the author if I go ahead and fix the issue.

• Seems to be working well with 1.0dev, so I added the 1.0 tag to the project wiki page.
• I had to change the import from from tracextracturl import extract_url to from tracextracturl.extracturl import extract_url. I think this could be avoided by modifying __init__.py in ExtractUrlPlugin.

(In [11890]) Fixes #6940, #8680:

• Removed setup_requires statement from setup.py. The listed package is only necessary for installation, not for running setuptools.
• Modified import statement for extract_url since it was not importing correctly.

Tested with Trac 1.0dev-r11167.
