Prametrize !includedir

Hardcoded path provided by puppet is now replaced by providing only the final directory as on
most systems includedir is provided by package and it's matter of user to provide it if he
wants to override it. This also allows disabling including at all.
Add Archlinux support

This commit adds Arch Linux support. Everything besides bindings for JAVA and
Ruby has been tested as properly working. JAVA and Ruby bindings cannot be
managed by puppet as official packages are not in official repositories but in
AUR instead. PHP bindings are installed by default with mysql/mariadb package so
there is no need to specify/install separate patches. To reflect this,
bindings.pp has been altered to throw a warning if user wants to install
PHP binding. It throws an error is user tries to install JAVA or Ruby binding.

Changed the backup user grant in backup.pp to use the ensure variable instead of always assuming 'present'
Fix problem with GRANT not recognizing backslash

If database grant has backslash in database name (for example: example\_dev), then puppet will try to apply same resource every run because MySQL reports that table name with double backslash (for example: example\\_dev). By global replace of double backslash with single one, this issue is fixed.
Update mysqltuner.pl to version 1.3.0
