Added CEmailValidator fix
Merge pull request #2602 from creocoder/idna2-fix

IDNA2 fix
Additions to #2602:

1. Proper Net_IDNA2 usage. Net_IDNA2::decode() and Net_IDNA2::encode()
accepts only domains, not full URLs. Before this fix framework used
to pass full URLs which is wrong usage.

2. If CEmailValidator or CUrlValidator is being used under PHP 5.3.0+,
native `idn` PHP extension will be used (`idn_to_utf8` and `idn_to_ascii`
functions in particular). Otherwise Net_IDNA2 will be used (for PHP
< 5.3.0).
Fixes #2053:

1. CPasswordHelper has been refactored.

2. CSecurityManager has been enhanced and now able to generate
cryptographically strong random stuff.
