Now MySQL is no longer supported, we need to change the docs

This change refactors the pgloader instructions to have
less headings and be more straightforward.

Markdown renderers find it easier to determine
where lists start and end when lists are surrounded
by new lines.

For consistency, also ensure entries in the list
are aligned when they span multipls lines.

For the sake of consistency, removes any extraneous
consecutive blank lines from the doc suite.

Changed documentation of converting a MySQL-Database with Gitlab to a Postgresdatatabase. The instructions were missleading. See -> https://gitlab.com/gitlab-org/gitlab-ce/issues/2904

Closes #2176 (gitlab.com)

Introduced in
https://github.com/gitlabhq/mysql-postgresql-converter/commit/b2d1599706f532e1bac836243f25e005c816ef14

Running converter with Python 2.6.x installed gives the following error:
AttributeError: 'module' object has no attribute 'check_output'

After installing Python 2.7.x everything works fine.

This ensures that all tables created during the import belong to `git`.
If you import as a different user, such as the `postgres` superuser, you
may encounter issues where the GitLab database user cannot access tables
in gitlabhq_production, _even if_ `git` is the owner of
gitlabhq_production at the time of import.
