Cyclic preferences are no longer normalized fixing issue with cyclic plotting code

ATTENTION: This commit will break any custom analysis code, which
assumes cyclic preference values have been normalized between 0 and
1. Cyclic preferences are now stored unnormalized but are normalized
with the cyclic_range parameter before plotting. Make sure that if any
of your analysis code depends on the preference values being
normalized, that you do the normalization yourself by dividing the
preference values by the cyclic_range accessible on the sheet_view
object. Note the Corner_OR, Orientation_Preference and
Spatial_Frequency_Preference test data has been updated to reflect the
change.
Added main topographica directory to search paths to allow images, examples, etc. to be found by resolve_path when Topographica started from other than the main directory

run_batch now has metadata_dir parameter to control metadata output
Reorganized _find_version(), made it give more information in case of errors, and made it more robust against unexpected input
Made git version checking robust against extra non-version-related tags, such as those added by Jenkins.  Fixed default version number fallback.
Added tip about Inkscape

Cleaned up output directory handling, in part for Jenkins support.  Moved default output path code out of topo/__init__ and into topo/misc/commandline.py, so that it can be overridden by setting param.normalize_path.prefix in .topographicarc or through a new option -o <path>.  Made topo/tests/test_script respect param.normalize_path.prefix and avoid creating an output directory when loaded, postponing that until the functions are actually run, to avoid creating spurious output from nose.
Merge branch 'master' into featuremapper
