Incorrect PHPDoc syntax

[sitnikovv]

Please correct the descriptions in the PHPDoc format to match the PSR-5.
To do this, you need to add its type in front of the variable name, for example:
It was:

/**
* Adds a password to a master key.
* @param $mkey A master key.
* @param $pwd A text password.
* @return true if otherwise operation.
*/
public static function addPassword (CompositeKey $mkey, $pwd)

It became:

/**
* Adds a password to a master key.
* @param CompositeKey $mkey A master key.
* @param string       $pwd  A text password.
* @return true if otherwise operation.
*/
public static function addPassword (CompositeKey $mkey, $pwd)

Without this, it is impossible to write, any normal IDE indicates a type mismatch (for example $pwd):
Expected \KeePassPHP\A, got string (@PARAM $pwd A text password.)
