GRD vertical grid reading assumes two whitespace characters between each number

[paulAtSafe]

The code that reads floating-point numbers from GRD files assumes there are multiple whitespace characters between each number.

For example, a line like this:

1.2345 -2.3456

will read two numbers: 1.2345 and (positive) 2.3456

To reproduce, remove extra whitespace from the shipped WW15MGH.GRD file and attempt to apply the EGM96 grid. It will fail to load (the first time only - but the ._96 file produced will be empty and no grid shifts will be applied after that).

I've attached a patch which resolves this issue.

Corrected at revision 2675. Clearly a coding error in the CS_extractDbl function in the CS_general.c module as reported by the user. The provided patch file was used as the basis of the correction, but could not be used directly as the patch file was out of date at this time.
