There are some problems on staging while testing #1782

[dchiller]

1. Without editing permissions, the spacing between the filter table and the results table on the Source Browse Chants page is non-existent.

2. The description and bibliography fields on the Source model were the first one's given a markdown editing and display widget introduced in Add markdown-powered fields #1749. But existing values are not shown because they contain html tags. We should turn this off for display until old descriptions are edited.
3. The browse chants is taking a long time to load and leading to timeouts... looks like the bulk edit form added a huge number of queries...
