Reporting Phase II: Custom Reports

Create Custom Reports feature.

This feature allows an end user to create a report with a degree of control not afforded by dossier.

Report Administrators are able to define 
1. what data set they would like,
2. how that data should be formatted (within reason), and;
3. simple filters which reduce the data set reported.

Once defined, a report can be run by another end user by assigning them the "Run Reports" security option.

Here's a 10,000 foot view of how it works:
Report Administrator goes to report dashboard, and selects Add New Report from the Custom Reports box.

Select a title and category, and enter whatever content you want to have in the report. Report Body field is rendered by a Mustache loop.

Optionally, add filters. Format is: field:value . Separate multiple values with a ';'.

Hit view or select the title to run the report. This will redirect to the show page and render the report

Testing: I've got us to a gig of tests with this feature. 'nuff said.
