ENHANCEMENT Moderator UI using built-in GridField
ENHANCEMENT Moved categories UI

Makes more sense for categories to be defined at the ForumHolder level and applied via drop down to each Forum (as a single field this has been moved to the main tab).
DOCS No longer requires TagField module

I have also adopted this module, since I am interested in anything that help people connect and share knowledge online it fits my philosophy :)
DOCS Update the installation doc

Mention composer as a recommended way to install, also that manual directory can also be used.
DOCS fix typo

FEATURE: Apply design to forums

Generic theming for forums. Designed to pick up as much from the base
theme as possible, whilst still providing enough structural styling to
make the forums usable out of the box. Has been tested in Dew, Simple,
and SSExpress themes.

This is a major change in some ways, as previously the design component
of forums has been very minimal. However, without design the forums
module is one of the most confusing and inaccessible so I do think it
needs to be done. The changes within the templates themselves are
mostly around turning multiple tables, and divs styled like tables,
into one table, and moving a few of the elements from the header to the
footer.
