Multi + DataValidator + custom validators not usable

[AlexP11223]

Looks like using Multi with DataValidator and custom validators (inside both of them) with custom error codes is not possible.

Both Multi with DataValidator call logger, which then checks error codes.

So

• if custom logger (with new messages) is passed to both of them - duplicated messages.
• if only Multi (or DataValidator) has the custom logger - the other one throws exception because its' default logger doesn't recognize custom error codes.

(I need DataValidator inside Multi because besides the form fields I need to validate the whole request to detect too big file uploads, but I guess it can be reproduced with other combinations too)

@AlexP11223 it seems you know the codebase better than me, I don't use this since long time and last time I worked on something here was 4 years ago. So... do you have any proposal or idea how this can work?

[AlexP11223]

No proposal :(
This "logging" stuff seems quite confusing and complex to me.

Also found some other problems:

• DataValidator skips non-existing fields, no way to make it required.
• Something unclear with messages possibly related to inclusion of field name in messages by default, maybe solvable via error templates.

Probably will switch to https://github.com/Dhii/validator for now :)
