blt should have an acsf:init:drush command

[nikgregory]

Since a lot of the blt action will do a composer update, acsf:init can be overkill once executed. But when acsf is updated, the drush commands need to be run or the factory will not deploy the code.

if we add a drush only command, we can let composer deal with the update and make sure the proper files are in place

<target name="acsf:init:drush" description="Refreshes the acsf settings and hook files.">
    <echo>Executing initialization command for acsf module.</echo>
    <drush command="acsf-init">
      <option name="include">"${docroot}/modules/contrib/acsf/acsf_init"</option>
    </drush>
    <echo>Please add acsf_init as a dependency for your installation profile to ensure that it remains enabled.</echo>
    <echo>An example alias file for ACSF is located in /drush/site-aliases/example.acsf.aliases.drushrc.php.</echo>
  </target>
