Improvement: variables with unlimited arguments

Syntax: <%= variable_name("foo", 3.1415, other_variable(10)) %>
Now you can call content. methods with any number of arguments, where argument can be string, number or other variable.
All variables in arguments will be prefixed with content, if they are not found in local scope.

Also: fixes and hex number support.
