The BLOGROLL_WIDGET_NAME and SOCIAL_WIDGET_NAME settings are now
respected by notmyidea if they are specified in your config file.
They override the default names of "blogroll" and "links" in the
notmyidea theme.
Used default() in template to simplify template code.
Renaming BLOGROLL setting to LINKS, changed default also.
Updated tests to check 'links' instead of 'blogroll'.
Whoops; links, not link.
This replaces all `http://` and `//:` links with `https:`. The protocol-
relative URL scheme is now deemed to be an anti-pattern. There are
security advantages to using HTTPS, and there are no significant
performance concerns.
In short, if the asset we need is available via HTTPS, then that asset
should always be loaded via HTTPS.
Fixes#1736
