w3m configuration

My only changes are to the colors, but everything was written.
Allowing .bashrc to be re-sourced.

Preventing paged output from prematurely disappearing.

The less pager tends to use an alternate screen where possible, restoring the previous screen state when it exits.  The -F option makes it exit early if it's not necessary, because there's only a screenful or less to display.  This combination of facts makes it completely broken when not used inside a terminal multiplexer that doesn't emulate the alternate screen.
Switching paged aliases to use the PAGER setting.
Merge branch 'master' from upstream
