The client and scp config ajax request only contain the settings for the
multi-file upload widget. So it doesn't need to be fetched unless the widget
exists on the page

  - Logo selection radio buttons not vertically centered (Firefox)
  - font-size value incorrect in login.css
  - Incorrect : placement in FAQ category edit
  - Incorrect block width declaration (700 vs 700px)
  - Browsers disagree on the placement of CSS3 outline properties
  - Correctly place check boxes and radio buttons

We should move initial data out of the install SQL file, which will make way
for a few things:

  * Internationalization -- which breaks the migrater model currently.
        Moving the data outside the install script makes it translatable
        without changing the SQL hash
  * Review -- Migrations which add more data don't highlight new features
        that need review to the adminsitrator

Uses a seven step procedure:
  1. (user) Fails to login twice or more
  2. Clicks the 'Forgot my password' link on the login form
  3. Submits the username or email address and triggers a password-reset
     email
  4. Clicks the link in the email and is directed back to the reset page
  5. Enters the username or email again and is logged in
  6. Password change is forced, but current password is not required
  7. Password is updated, user can continue the session without
     authenticating again

Use %config table by default for config classes

Add lastModified() method to retrieve the time of last modification for a
configuration key

Add $defaults to the specified on a subclass. The defaults remove the
necessity to specify a default value for each getter method, and, the
defaults are integrated into the array retrieved from getInfo()

Use mysql connection timing as the random seed, along with the microseconds
of the current time.

After merging the custom logo patch, the logo on the offline page
disappeared. This addresses the issue by exempting the logo.php script for
the offline redirect in client.inc.php

Do numeric comparison on db versions

Administrators are allowed to upload one or more logos and then select from
the uploaded logos to set one for the client site. Logos can also be deleted
on settings->pages submission

Previously, username and password were required. With this patch, the
email address can be used to authenticate the user with the password

Support MariaDB version 10.0 and forward, which previously did not appear to
be 'greater than' version 4.4 as in php '10.0' < '4.4'. Performing a split
by the dots allows php to perform a numeric comparison.

Make API requests stateless

This will facilitate a web-based export significantly easier

Some mail clients and servers (like the ones developed in the northwestern
United States) sometimes place encoded and non-encoded data in an email
body declared with "Content-Transfer-Encoding: base64". imap_base64 will
refuse to decode the body if it contains non base64 characters (like a
period, colon, apostrophe, etc). This patch uses base64_decode as a fallback
which will make a best effort to decode the data. In the case of our test
mails, the decoded data will contain garbage where the non-base64-encoded
data was in the original mail, but at least the message is preserved.

Disable DB session storage. This chews up database space and processing time
for a request that will never resume the same session (given the current API
model anyway).
