tables load content inefficiently

[fynnos]

the frontend loads the document table (search results etc.) very inefficiently:

1. it retrieves the document IDs from the server (search result)
2. for each ID it loads sDoc data
3. for each ID it loads other related data such as tags

this results in high system/database load and slow loading times for large projects

recommended solution:

1. search request should not return IDs but the full data required to show the table (sDoc + tags etc.!)

fixed in #525
