sites need to be reverified to take effect.

we also take care of regenerating the .htaccess even though it's not
actually necessary. this is because core status will warn us if the file
is out of date

this is important for SSL certificates which may be symlink to files
that are unreadable by Aegir (which is fine, as Apache can read them
because it starts as root).

I assume the impact on other uses of ->exists() will be negligible.

See #2046249.

This reverts commit 4f9541e5.

Issue #2044251: Remove '@none' from call to drush_invoke_process(), since it isn't supported in Drush 4.5.

Nginx: Make upload progress configuration compatible with latest release of Nginx extension and integration module for Drupal 7.

this fixes a regression introduced in the fix for #1678876

according to RSA security and most sites I could read, 1024 was
recommended until 2010-2015 and 2048 is now the recommended length for
more sensitive data. we are therefore taking the safest route.
