Extended form validation

[eluser]Patroklo[/eluser]
Hi, we have extended the form validation library that devbro made some time ago and added some new methods about time and date validation. Also we have tweaked a bit the file upload validations to get rid of some bugs and use real mime validation instead of only extension validation (that gave the user the chance of uploading illegal files only changin the extension of the file).

Both librarys have the same methods as described in the next comment.

If you think that there are some new validations that could be useful and we haven't added it to the library, don't hesitate to tell it to us and we will try to add them asap.
