On macos, the libexec directory for languagetool, as installed by brew,
lives in a version directory. To find the jar, we need to increase the
search depth, since the version directory will change with every version.
Example of brew-installed languagetool:
--------
$ tree -L 2 /usr/local/Cellar/languagetool
=>
/usr/local/Cellar/languagetool
└── 4.6

setting +write-mode-hook had no effect because +write-mode-hook was not
defined yet, it is only defined by the minor mode definition inside
autoload.el (which didn't get autoloaded yet).
Due to this when activating `+write-mode` the `mixed-pitch-mode` did not
get activated.
Fix this by moving these all to autoload.

Caused by langtool-langauge-tool-jar not being set (because defvar won't
change a defined variable), and app/write/doctor.el uses it in a
file-exists-p call, which throws the stringp error if given anything
other than a string.
This removes the various doom-line-number* variables and replaces it
with the Emacs 26 display-line-numbers API, which I've ported to Emacs
25.x (however, it uses nlinum under the hood, and not all of
display-line-numbers options are supported).
+ Make synosaurus unconditional
+ Move much of +write-mode into its hook
+ Conform README.org to template and expand it
+ Try to guess langtool-language-tool-jar
+ Update init.example.el entry
+ Remove redundant variables
+ Add +write-text-scale & +text-line-spacing variables
