Use the pythonrc Python startup script added as a submodule instead of
fiddling around with a script to build a (not really working) version
for myself.

- Also, silence a few shellcheck alerts, aren't relevant.
- And finally small change to ddg search, mainly aesthetics.

- Replace urlencode/ urldecode with Python3 instead of Perl.
- A little cleaner json_tool usage.
- A Python3 only (no Python2) AWS region deducation.

- Added monitor alias to notify on command finish or failure.
- Better use of Python's json.tool.
- Little tweaks.

__run_duration returns 0 when it can't calculate the command run duration (when the shell doesn't have support for PS0, like ksh).

Rewrote prune_prerun (prune prerun files used to time shell commands) because grep on OpenBSD doesn't have support for null-terminated strings.

- Added shell function to echo with color.
- Added shell alias to alert (bell).

A new shell script, `wrapper`, that (similar to what git does) in case an
excutable of the format `command-subcommand` is available (command being
the name called, $0), calling `command subcommand` will be call
`command-subcommand`. For example: calling `docker dev` will call
`docker-dev` if such an executable exists. So now `docker` (in
`~/Documents/bin/` is a symlink to `wrapper`. Changed my docker shell
aliases to scripts.

- Don't use containerized or virtualenv'ed for cli apps that are not part of a project (besides Docker isn't available on the BSDs).
