JSON API authorization: Fix error comparing signatures when the WordPress installation is using site_url filters.
Update widget-conditions.php

Better to use add_filter() than add_action(), for readability.
Allow All Instances of Sharing Meta to Save

Sharedaddy registers its meta box for all public CPTs by default (line
25), but only saves the option in the meta box for posts and pages. The
`sharing_meta_box_save()` function needs to save the meta box's
information for all CPTs to which the meta box is tied.
Share my deploy shell script around.
Don't try to use the sharing class if the module isn't loaded - just default to no status. Prevents fatals. Props Joey

prevent error in post_login_form_to_signed_url

In some instances, when the `$parsed_url` doesn't have a `query`, the `post_login_form_to_signed_url()` function would emit a php notice and thus return an invalid result, which would then fail the signature checking process and thus the authentication flow would fail.

This prevents the "Someone may be trying to trick you..." notice to appear in the wrong context.

Discovered this bug while helping one of our API users debug an issue (see https://github.com/snarfed/bridgy/issues/161#issuecomment-45287830)
concat $url instead of overwriting it
