Modify sniff for "Implements hook_foo_BAR_ID_bar() for xyz_bar()"

Problem/Motivation

Per Doxygen and comment formatting conventions for documenting hook implementations and theme preprocess functions, hook implementations can also refer to a template file, e.g. Implements hook_foo_BAR_ID_bar() for xyz_bar.tpl.php. (See #1443202: Apply documentation standards for hook_preprocess_HOOK() for examples.) The function comment sniff therefore needs to support the additional option.

Proposed resolution

Expand the regex to support the additional option.

Remaining tasks

Test and commit the patch.

Original report by Lars Toomre

According to @jhodgdon in #1533244-22: Make help module pass Coder Review point b),

Format should be "* Implements hook_foo()." or "Implements hook_foo_BAR_ID_bar() for xyz_bar()."
* Implements hook_preprocess_HOOK() for block.tpl.php.

We should also file an issue with Coder for this one, because "for *.tpl.php" is acceptable syntax for this.

This is an issue to address this false positive sniff.
