More VAT code support

Improvements

• Added support for Swiss VAT codes - #3

vatcode-validator 1.0.3

Includes some new patterns, some corrected patterns, and some misc changes for maintaining the module.

Added patterns

• BG codes

Corrected to patterns

• FR codes don't allow O or I characters
• GBGD codes only allow 0 to 499
• GBHA codes only allow 500 to 999
• RO codes can be 2-10 digits

Other module changes

• Reorder patterns to be alphabetical so they're easier to audit manually.
• Test failures are output in red so they're easier to see.
• Test process has status code of 1 on failures (and still status of 0 on success).

vatcode-validator 1.0.2

Now accepting spaces in all VAT codes. This will hopefully make it better for front end use to validate a users VAT code syntax.

vatcode-validator 1.0.1

The first release of vatcode-validator, takes in a VAT code and validates its form. Works on any EU VAT code, checking it's syntax (not it's validity).
