Rename mail utility programs (yet again), to be prefixed with `mail-`
instead of `neomutt-`. Also did not substitute with other MUA like
`aerc-` since these utilities are mostly independent of specific
implementations.
The very specific `neomutt-filer` implementation script I completely
removed since for aerc the same can be achieved with a simple
configuration option.
Mails get symbols in the flag column if they are sent by me, CC or BCC
me, or they are tagged as a 'list' (from a mailing list).
Added some additional info to status bar (current folder, recent and
unread counts), and extended the flag column slightly to accomodate more
flags.
Starting to replace neomutt in my workflow with aerc:
it is a little more lightweight, directly supports notmuch directories
and has a relatively sane configuration style (mostly just ini-like)
with 'go-templating' baked in.
In general, the configuration just feels less 'cobbled-together' than
before. I can make changes without worrying what other things are going
to break by doing so. I understand the complete configuration and
styling, instead of mostly relying on other people's formatting lines
for the styles.
I am still learning some of the configuration possibilities but it
already functions as a neomutt replacement.
