Remove System Check for Date Extension

[cmb]

Hello Community,

since the System Check was introduced in CMSimple_XH 1.5.4 it checks, if the Date extension is loaded. However, the date functionality is not offered by an extension in PHP 4 (the check results in a warning), and in PHP 5 it is not possible to disable the date extension (cf. http://www.php.net/manual/en/datetime.installation.php).

So I suggest to remove this check for CMSimple_XH 1.5.x and 1.6.

JFTR: this has been done for XH 1.6 (r950).
