RELEASE 0.1.1

Changes since v0.1.0:
* Fixed a bug in uaparser_os
* Removed unused function from uaparser_os
* Simplified check_user_agent function
** Don't need separate functions to check for aliases
    and exclusions; now use local contains function
** Switched contains to use a tail-recursive
    short-circuiting boolean expression instead of
    lists:all (with a fun and case)
* Removed unnecessary OTP modules (app and sup)
* Fixed/added specs; fixed dialyzer warnings
** eunit tests almost made it in, but introduced dialyzer
   warnings in several contexts; working on suppressing
   those
