Fixes to make_uh and formatting changes.

- Major speed improvements in make_uh due to the use of np.convolve rather than pure python convolution as was previously implemented.
- Some pep8 fixes but there are still some issues.
Changes to allow for routing on the same grid as the target domain.
i.e. if REMAP = False and AGGREGATE = False.
quick fix to parsing of outlet names
Add C convolution routine for speedup

-Also changes to structure of ring and unit hydrographs.  Changes are internal and are backward compatable.
-Fixed bug in agg_tsteps logic
Merge remote-tracking branch 'github/hotfix.0.0.3'
small fix to rvic/c_convolve.c syntax
remove r+ read from forcings files
fix minor typo in c_convolve and remove extra astype call in read_forcings
simplification of c_convolve.c
fixes to fraction2domain.bash, double prec fraction and fix to land mask ncap2
Reworked search catchment.

Speed and algorithm improvements:
- Tracks and saves path - either in or out of catchment.
- If new path encounters a point that is out (-1) or in (1), the paths are joined and we break out of the search loop
- Still tracks path length (cells / count_ds) and returns sorted arrays for make_uh computations.

This is likely to have significant speed up implications for large basins.
Fixes to north south indexing convention.

The formalized convention is now: the y-dimension 0-index position
corresponds to the highest latitude.
add better fractions plotting routine.
updates to read forcing and history file unit conversion
Improvements to RVIC parameter file generation processes

- now allows input pour points file to include x and y index locations (0, 0) is nw flow direction domain corner
- now correctly checks for latitude order after remapping
- now includes two new variables in output parameter file (outlet_upstream_area, and outlet_upstream_gridcells)
- fix to VIC flow directions
