>          Issue Type: Bug

> If you enter a Number in a Currency-Field with a decimal separator (other than ".") and
without trailing currency symbol you get a parse Error.
> Test Case - Type in JS Console:
> var tr = new TrNumberConverter( null, "currency", "de_DE" );
> tr.getAsObject( "20,50" ); // Parse Error
> tr.getAsObject( "20,50 €" ); // Working
> tr.getAsObject( "20" ); // Working
> Cause:
> The Method TrNumberFormat.prototype.removePrefixAndSuffix will fail, if not both matching
Prefix and Suffix for Positive or Negative are present. If only one of both is present an
exception is thrown and parsing fails.
> Since the Prefix for positive Currency is "" (the empty string) it will always match
and try to find the matching suffix "€" or fail.
> In the case of an exception the default parseFloat is used as a fallback, which works
for default english notation, so plain Numbers and using the dot as a decimal separator will
work.
> Expected Behaviour and proposed Fix:
> Entering a locale Numberformat without Currency Symbol should be parsed without giving
an error. The removePrefixAndSuffix Method should be more lenient and also accept input without
currency suffix.
