* Fix chktex highlighting wrong column when using tabs instead of spaces
Fixes#723
chktex implemented feature request [1] for allowing setting options from
the command line. Thanks to that we can tell it to treat tab character
as of one space width, i.e. one char. That means, after we translate the
output back to Vim columns, we get correct numbers.

* Add test_tex_chktex.vader
* Use functions to set g: variables in ale_linters/tex/chktex.vim
* Update ale_linters#tex#chktex#GetCommand() to use '%e'
* Add chktex linter
* Alias plaintex to tex
* Add lacheck linter
Closes#179
* Add the chktex warning code
This very useful to have when you want to suppress lint warnings with LaTeX
comments. chktex tends to be a bit noisy so this often needed.
* lacheck: Make regex less specific
To be more robust future changes in `stdin-wrapper`
