Formatting changes for the MAILING-LIST-SETUP doc

Added some formatting changes for the MAILING-LIST-SETUP doc to make it
easier to read.
Option to change the email subject prefix

It adds a new setting 'email_prefix' to configure which [label] will be used in the subject of emails. Discourse currently uses '[title]'. The problem is that sometimes you need to set a longer title, that doesn't really work well for emails. I think this is very common since the HTML `<title>` tag is very important for SEO.

It will default to '[title]' if this setting is not used.

See: https://meta.discourse.org/t/where-to-change-the-email-subject-prefix/11989

Align basic-topic-list table structure with Categories page topic-list table structure

This is an optimization for people that choose their table row highlighting to be inverse of the default Discourse theme.
If people choose to have the heading row (or individual th columns) and 'even' rows highlighted in topic-list.scss for the Categories page, the alternate coloring is not carried over to the User Activity page's Messages list. Because the basic-topic-list table there doesn't use the THEAD and TBODY wrappers, the first data row is effectively an 'odd' row, so highlighting is now applied both on the heading row and the first data row.
By adding the THEAD and TBODY wrappers, we make sure that the table structures across the app are the same and global row highlighting styles work out of the box also on the User Activity page.
