Removing spaces from process input identifiers.

Following 3f286a027062b0eaa86fb48784f3552f7dadecc6, this removes all other occurrences of process inputs with spaces in their names.  The gt-process-feature and gt-process-geometry tests still pass with this change (not surprising, since they don't make use of input names).
