(Enhancement) Validator: Adding more concrete base64 validation, Enabling []int validation

[marcsantiago]

The current base64 validator makes a few assumptions about the nature
of the base 64 string as a result of using regex.
By using Go's build in base64 lib we circumvent the regex as well as
adding full functionally to validate both standard base64 strings
and raw base64 strings.
This is an additive string, which allows for full backwards capabilities.

(Enhancement) Validator: Validating contents of []int …
Adding a new type to enable the ability to validate what's inside of an
int slice. This is important for structured API documentation, when the
items in the slice should be known integers. I didn't implement the other
slice types as I don't have a use case for them, but it should be easy
enough to extend. This is not a breaking change.

Thank you!

@marcsantiago could you please take a look at unit tests?

./validator.go:1202:26: invalid argument customErrorMessage (type tagOption) for len
./validator.go:1225:45: cannot use customErrorMessage (type tagOption) as type string in argument to fmt.Errorf
./validator.go:1225:95: too few values in struct initializer
./validator.go:1228:127: too few values in struct initializer
./validator.go:1230:130: too few values in struct initializer
FAIL	github.com/asaskevich/govalidator [build failed]

[marcsantiago]

Of course, sorry about that, I'll give it a look today.

@marcsantiago which Go version are you using? Tests are falling at golang:1.9

[marcsantiago]

go version go1.10.2 darwin/amd64

[marcsantiago]

I think the fails are unrelated to the PR, if you diff the changes customErrorMessage was never touched, in fact every change is additive with thier own tests... with the exception of println to fmt.Println in the validator_test.go file
