Group projects with common prefix
Power users "group" their projects using a shared prefix before a pipe | (for example Balsac | XXX and Balsac | YYY).
The frontend should group these projects together under a shared title.
The current corpus list display as a table must be extended:
- add a
<tr>for each group, where a large title displays the prefix (Balsacin our example) - sub projects are grouped together below, with a visible indentation
- projects without groups are displayed at the root level
- alplhabetical order must be preserved
- filtering capabilities must be preserved
