version 1.2 - start
- Change in browscap.ini version 5020 to temporarily fix a bug with
parsing user agents with "+" (plus) sign in the match string. See:
https://groups.google.com/forum/#!topic/browscap/s9zGyRBIvK0
  This also allowed me to remove some user agent overrides from
BrowscapWrapper.class.php
- Added `require_once` for required files
- removed timers from the code
- changed getting the user agent string to just calling
`$_SERVER['HTTP_USER_AGENT']`
- added UserAgentInfoConfig class for easier configuration
- changed the cache classes for easier configuration
- updated readme file to reflect the changes above, and added more
explanation about `->isBanned()`
