Various fixes

• updated translations for pt-br, it and fr
• less blowing up of php when an array is passed to a rule that expects a string
• don't add {field} to a custom error message if it already exists
• added a flag to force the required rule on empty fields

v1.4.0: Merge pull request #187 from notona/feature/fix-interger-validation

Validator::mapFieldRules() provides another way of adding rules on a per-field basis

Added a flag to validateInteger() to enable strict checking (bypassing PHP's automatic conversions)

Bugfix

• Fixed a bug where Validator::withData would erase all rules.
• Added test to make sure Validator::withData actually works as intended
• Added "Re-use of validation rules" to the readme

Massive thanks to @wenbinye for spotting the bug, and sorry for any inconvenience it may have caused
