Clicking on Submit button when at a /openrem/ct/hist/ URL from an acquisition data plot causes a server error

[David Platten]

When clicking on Submit when at a /openrem/ct/hist/ URL from an acquisition data plot causes a server error. This is because the underlying code that is called from /hist/ (dx_histogram_list_filter or ct_histogram_list_filter in views.py) defaults to a "study" histogram analysis if a variable called "acquisition" is not passed in the request. This code fails because one of study_description, study_dap_min, study_dap_max, study_dlp_min or study_dlp_max are not present.

[David Platten]

Added specific studyhist option and associated code for creating histogram data. Fixes issue #146. If neither studyhist or acquisitionhist is passed to dx_histogram_list_filter or ct_histogram_list_filter then the routines default to the same behaviour as the non-histogram filters.
