TPage::validate should return a value.

[sergeymorkovkin]

When validating different validation groups it would be very convenient to receive a validation result in return to $this->validate('group') call. This will let developers to write constructs like the following one:

if ($this->validate() && $this->validate('additional') && ...) {

}

Otherwise we'll need to write hard-readable code:

$this->validate(); if ($this->getIsValid()) {

$this->validate('additional'); if ($this->getIsValid()) ...

}

I think I need a better use case to accept this ticket. Redundant validation decrease performance and TPage->validate() is invoked in raisePostBackEvent so you only need to check the IsValid?-property according to what you are validating.
