Function: DateParse
Converts almost any date format to a YYYYMMDDHH24MISS value.
Parameters:
str - a date/time stamp as a string
Returns:
A valid YYYYMMDDHH24MISS value which can be used by FormatTime, EnvAdd and other time commands.
Example:
> time := DateParse("2:35 PM, 27 November, 2007")

Modified return values:
Partial date returns
No month : nothing
No year and no day : nothing
Time and no day :nothing
Month and year without time : substitute 1st for day
Day and month : substitute current year
No date and time still substitutes current date
Allow no separator aorund named months (eg 25May60)
Only alphabetic Month name follow on characters to prevent month taking first 2 digits of 4 digit year if there are no separators eg in 25May1960 year group only gets 60 and becomes 2060
Separators relaxed, can be any character except letter or digit
Search for named months first to prevent number month incorrectly matching in "Feb 12 11" as day =12 month=11 and skipping named month match
With named months day or year are optional
If numeric month is > 12 and day is <= 12 swap month and day (probably american date)
