Add link to opencs documentation on readthedocs, available through

context menu.
The documentation opens in default browser.

There are 3 contexts:
- global: opens the OpenMW CS User Manual main page
- when a record is selected: opens the "Tables" page
- when the filter field is selected: opens the "Record Filters" page

There is also a link to the OpenCS tutorial in the help menu.
