Colons (:) and accented chars in id

[Carlos Noguera]

Hi all,

In handlebars.js colons and accented chars are allowed (see http://tryhandlebarsjs.com/) 

Template: 

Goodbye\n{{x:cruél}}\n{{world}}!

Context:

{'x:cruél': "cruel", world: "world"}

compiles to:

Goodbye\ncruel\nworld!

Handlebars.java's parser however does not allow for these chars in an identifier:

com.github.jknack.handlebars.HandlebarsException: inline@79696ab:2:1: found: '{{', expected: '<EOF>'

{{x:cruél}}

 ^

at com.github.jknack.handlebars.internal.HbsParser.template(HbsParser.java:172)

....

this could be fixed by changing the lexer's rule for ID_START to include ':' and the UTF-8 range for accented characters:

ID_START

  :

   [a-zA-Z_$@:\u00C0-\u00FF]

  ;

unless I am missing something, this should not affect anything else right?

Carlos.
