6.7.7: Import ASCII meteo file: Date format: custom or YYYYMMDD | hh && multi-year import

[cj0]

I'd wish to import Royal Dutch Meteorology Institute data. These files come in an hourly format where the time field does only contain hours [1-24] and not minutes: http://projects.knmi.nl/klimatologie/uurgegevens/selectie.cgi

Now I do need to append the 00 with a Regex from "(\d\d\d,\d\d\d\d\d\d\d\d, [1-9 ]\d)" to "\100". Skipping the find and replace hassle in the ASCII files is welcome.

Next it would be ideal if multi-year files could be imported and converted to averaging values in a single run.
