For some reason CI tests started failing with these errors:
> ale_linters/eruby/erb.vim:1:1: Use scriptencoding when multibyte char exists (see :help :scriptencoding)
> ale_linters/mail/languagetool.vim:1:1: Use scriptencoding when multibyte char exists (see :help :scriptencoding)
Not sure at which point or what changed for this to happen but this MR
fixes it by removing the multibyte chars present on the problem files.

The executable for the Alex linter is currently hard-coded as 'alex',
which is an issue given the fact that it conflicts with the Haskell
lexer generator, whose executable is also called 'alex', has been around
a dozen years before the linter, and is packaged in the official
repositories of the major Linux distributions.
This commit adds options to use a local executable for the alex linter
(which is a node package), and an option to set a custom executable.
As side changes:
* The pattern in the alex handler is made more readable by turnig it
into a very-magic regex.
* Alex handles plain text, markdown, and HTML. Specific flags for HTML
and markdown are provided when instantiating the linters for the
respective filetypes, while before those formats were treated as plain
text.
Switches all vale instances to JSON output and provides an appropriate
handler for that. Without JSON, no end_col is provided and text
highlighting only catches the first character of every result.
