Colon not possible in TCA "displayCond" value
Currently a colon is not possible in the value of a display condition for TCA fields.
So something like this would does work:
The funtion "isDisplayCondition" explodes the string by the ":" character. So the example string is exploded into 5 parts but the 5th part is ignored.
The "explode" should be limited to 4 parts and 4th part should contain the whole string after the third colon.
