Unable to directly enter decimal values in a numberField

[jesse-c]

If you begin type the sequence of 0, ., 0, the input field will end up as "0", as opposed to "0.0", for the cases where you would be entering values such as "0.005".

A workaround is to type 0, ., 5, ending up with "0.5", and then moving the cursor in front of the 5, and entering the desired number of 0s.

This is caused by storing the field value as a Float, we should probably store the value as a String instead.
