The parser requires that floating point numbers include a leading zero digit, for example:

torin:~$ opa run
OPA 0.3.2-dev (commit ad52c56-dirty, built at 2017-01-16T17:34:27Z)

Run 'help' to see a list of commands.

> 0.5
0.5
> .5
|
error: 1 error occurred: 1:2: no match found, unexpected '.'

The parser should be updated to support FP numbers with and without the leading zero digit.

Improve floating point literal support

These changes update the grammar to allow floating point literals without an
integer part, i.e., just the fraction part (.1, -.1, etc.)

Fixes open-policy-agent#215
