Coma separator handling in greaterThan and lessThen validators
fix country codes Dominica + Dominican Republic

DM is Dominica and DO is Dominican Republic. Several translations had
that mixed up, including U.S. English. Some translations may need minor
corrections still.
Replace ',' with '.' to validate decimal numbers correct.
New validators for input type file. Useful when multiple attribute enable.

New options:
- maxFiles: The maximum number of files
- minFiles: The minimum number of files
- maxTotalSize: The maximum size in bytes for all files
- minTotalSize: The minimum size in bytes for all files
