FlatFileParser can't handle complex mappings

[Nicklas Nordborg]

If you for example create a column mapping as '\Ch1 B Mean\ ' (note the extra space) you will get the following exception when importing data with it:

java.lang.NullPointerException

The problem is that the number parser is applied to the trailing space. This generates an exception since it is not a number. On the other hand, if this had been handled correctly, the CompoundMapper that is later putting together the result is not using the number formatter. This must also be fixed.

In this case the result would still be an error (NumberFormatException), since the space is still not a number.
