Unification of logging, added manager, location to logs.

This commit intends to fix a non uniform behavior of logging across modules, as well as
different implementation of logging. Some modules/files which intentionally implement
their own logging version have not been modified.
Moved chimeraguider to controllers; disabled expose commands to camera.
Restored import of chimera.core.log for files using setConsoleLevel.
cknowledged commit of chimeraguider to controllers!
Remove Chimera's copy of xml.etree
setup.py and requirements.txt sanitization.

Well, somehow, someday we started using both setup.py and requirements.txt
for dependencies definition. They were not in sync and apparently we
are not supposed to do this way according to some sources below.

This changes puts all dependencies data into setup.py alone and requirements.txt
now uses a special flag to use the dependencies from setup.py directly.

In addition I removed the Makefile and windows specific setup/NSI as those are
not supported and/or needed.

For Windows we'll have a wheel in the future to install it easier assuming you
already have Python/pip.
Merge Nelson's logging branch.

Some stuff were removed and will be merged back later (pyfits->astropy for instance)
