Link analyzers to documentation page

[jkppr]

Each analyzer has only a certain amount of real estate in the list of available analyzers to explain what it is about and how to configure it / get it working.

The feature idea would be to add a link to the documentation page for the analyzer on timesketch.org.

Example:

The hashR lookup analyzer has the following description: Lookup file hash values in the known hashes database generated by hashR.
If we would add a link to the documentation page that is added in #2824 it would allow users to faster understand what the analyzer is about and how to use them without spending too much space in the list for it.

An alternative idea:

Instead of linking to the documentation on timesketch.org we could also open the documentation page in a dialog and render the markup language.
