* plugins/base: code style improvements
Quote variables, use $@ and $array[@] instead of $*, typeset some integers, remove unneccesasary binary invocation, use shell features when possible, remove `eval`, &c.
* plugins/base: conditional function definitions
Instead of functions failing when required tools aren't installed, just don't define the function.
Alsö, don't redefine del() if it already exists.
* plugins/base: rewrite `usage()`
Reimplement disk usage function using Bash syntax and simpler layout, without having to invoke an external binary.
* plugins/base: revamp `quiet()`
New implementation that is even quieter.
* plugins/base: `myip()`
* plugins/base: `pickfrom()`
* plugins/base: `passgen()`
Fix `passgen()` to not need `tr`, remove one subshell, and eliminate a useless `echo`.
* plugins/base: `mkcd()`
* plugins/base: `mkiso()`
* plugins/base: remove `banish-cookies()`
Adobe Flash is gone with the wind. Alsö, this would be something someone would do *once* and shouldn't be a function...
* plugins/base: `lsgrep` is SC2010
The `lsgrep()` function is *itself* explicitly forbidden by `shellcheck` rule SC2010.
Alsö, s/`$*`/`$@`
* plugins/base: `mkiso()`
Expressly handle unbound parameters.
* plugins/base: remove `command_exists`
* plugin/base: lint SC2154 && SC2144
Newly undisabled `shellcheck` rules
* plugin/base: import libs for tests
* plugin/base: `shfmt`
Apply `shfmt` using current project settings. My apologies to future `git blame` hunters. ♥
- Remove limitation on OS.
- Add search for Mac OS X developer tools locations by using `xcrun` instead of trying to guess paths.
- Add search for locations based on path of `$GIT_EXE` (set by `lib/theme`).
Addresses bash-it/bash-it#1632
And use `_log_warning`.
Alsö, code style cleanup: quote things, handle unbound parameters, &c.
Alsö alsö, short-circuit if not installed or inadequate _Bash_ version.
Short-circuit the loader rather than indenting nearly the whole file.
ALSÖ, assign the `_pip_completion()` handler directly once it's loaded so that we get out of the way once we load it.
Convert from indented if-block to return then unindented code. This should have basically one line change at the top, one line removed at the bottom, and then all whitespace.

New function to do a search looking for a sibling to a parent of the current directory, for example to find `../../.git` to indicate that `$PWD` is inside a git repository.
