api 7.x-1.2

Changes since 7.x-1.1:

1. Bug fix: The parsing code had a problem when encountering two closures (which amount to unnamed functions) in the same file during parsing, which would cause a fatal database error. That is fixed -- unnamed objects are now not saved as documentation objects. (There was a vendor file in 8.x that triggered this problem.)

2. Feature: YAML, CSS, and a few additional file types/extensions are now parsed/displayed as plain-text files.

3. Feature: You can now exclude directories from parsing by regular expression. This was done because Drupal 8.x core has a lot of vendor test files that we don't need to parse/display on api.drupal.org. These can now be excluded using the regular expression |/vendor/.*[Tt]est|

4. Minor stuff:
- The Overview page now shows the node cleanup counts along with the other queue counts.
- There is a drush command to show the status
- PHP 5.3 is listed as a requirement in the .info file (Grammar Parser requires it)
- During update.php update hooks, if all files are reparsed, the parsing queue is cleaned out too
