view_project_panels.html:
- increase modal height to make room for fcs_text field
- add icon with link to remove a panel's parameter

decorators.py:
- add panel_parameter_id to list of checks for requiring a project user...really need to figure out a better way to restrict view access to a project's user

models.py:
- added fcs_text field to PanelParameterMap...this will hold the FCS file's PnN value which helps us identify which channel goes with what parameter
- added some more validation checks in clean(), particularly making sure the a parameter/value_type combo is unique in a panel, and that a fcs_text is unique within a panel
- collect all the validation errors in a list so the user can see them all at once not have to discover them as they submit the form multiple times

urls.py:
- new route for removing a panel parameter

views.py:
- new view for removing a panel parameter
