Enhanced sponsor admin page
For #67:
* admin list sorted by name
* not limited to 100 per page
* a sortable visual indicator for each sponsorship benefit
(completed, missing, not applicable)
* also the sponsorship level, admin contact name, and an active
or not indication
* the ones we have today: print logo, web logo, print
description, web description and the ad.
* an action pick list like “email” and check mark the sponsors
* I want to email based on the assets that are missing.
* in subject and body, replace %%NAME%% by sponsor name
```
