* README.rst: tidy up redundant instructions
Remove the README section which detailed how to force `psycopg2` 2.7 dependency installation from source rather than binary.
`psycopg2` 2.7 would automatically favour installation from binary. A bug affecting some users made it desirable to have the option to install from source instead. The README detailed how to do this using pip's `--no-binary` option (nice!).
`psycopg2` 2.8 has now split the binary and source dependencies into different packages with different names (source: [psycopg2 docs](http://initd.org/psycopg/docs/install.html#change-in-binary-packages-between-psycopg-2-7-and-2-8)) which makes the `--no-binary` instructions redundant. To specify source/binary you now need to explicitly specify the desired package.
As of #1060, installing `pgcli` from pip will result in the installation of `psycopg2` 2.8 from source.
* README: additional instructions for psycopg2 2.7 users
Anyone limited to psycopg2 2.7 may still encounter some known issues when installing from binary.
Add a link to the README to acknowledge this, and help those users install it from source.

"\pset pager" has three possible values: "always", "on", and "off".
pgcli previously treated all non-"off" values as "always". This change
implements the expected behavior, which is to use the pager when the
output is larger than the terminal height (See \pset pager in
https://www.postgresql.org/docs/9.2/static/app-psql.html). Pgcli adds to
this by also using the pager when the output is wider than the terminal
width.
Fixes#813
