Feature: #63561 - Add TypoScript stdWrap strtotime

See Issue #63561

Description

A new TypoScript property strtotime is now available within stdWrap which allows for conversion of formatted dates to timestamp, e.g. to perform date calculations.

Possible values are 1 or any time string valid as first argument of the PHP strtotime() function.

Basic usage to convert date string to timestamp:

date_as_timestamp = TEXT
date_as_timestamp {
        value = 2015-04-15
        strtotime = 1
}

Convert incoming date string to timestamp, perform date calculation and output as date string again:

next_weekday = TEXT
next_weekday {
        data = GP:selected_date
        strtotime = + 2 weekdays
        strftime = %Y-%m-%d
}

Impact

The new property is available everywhere in TypoScript where stdWrap is applied.
