Disabled deployment from Travis-CI.

I have found it to be very buggy.
Fixed bug where '.' was treated as '0'.

The strategy to catch corner-cases like '+', '-', '.', 'e', and 'E' has
been revised to be less case-by-case specific, and more general
as to catch many different, unforeseen corner-cases.
Updated documentation and upped version.
fastnumbers version 0.1.4 release.

 - Fixed bug where '.' was incorrectly identified as a valid
   float/int and converted to 0.  This bug only applied to the fast_*
   and is* functions.
 - The method to catch corner-cases like '.', '+', 'e', etc. has been
   reworked to be more general... case-by-case patches should no longer
   be needed.
