mod_http_oauth2: Tweak method of centering the UI
The percentage here was relative to the viewport width, which on some
very wide screens may put the UI slightly outside of the view, requiring
scrolling to see.
By using a unit relative to the height of the viewport, this is avoided
and should work better. But no guarantees, it's still possible to resize
the browser or adjust font sizes so that the UI goes out of view.

--- summary: Distrust servers with too small keys ... Introduction ============ This module sets the security status of s2s connections to invalid if their key is too small and their certificate was issued after 2014, per CA/B Forum guidelines. Details ======= Certificate Authorities were no longer allowed to issue certificates with public keys smaller than 2048 bits (for RSA) after December 31 2013. This module was written to enforce this, as there were some CAs that were slow to comply. As of 2015, it might not be very relevant anymore, but still useful for anyone who wants to increase their security levels. When a server is determined to have a "too small" key, this module sets its chain and identity status to "invalid", so Prosody will treat it as a self-signed certificate istead. "Too small" ----------- The definition of "too small" is based on the key type and is taken from [RFC 4492]. Type bits ------ ------ RSA 2048 DSA 2048 DH 2048 EC 233 Compatibility ============= Works with Prosody 0.9 and later. Requires LuaSec with [support for inspecting public keys](https://github.com/brunoos/luasec/pull/19).
