Merge branch 'ungrib/9-char_varnam' into develop (PR #216)
This merge enables support for 9-character variable names in ungrib. Prior to
the changes in this merge, variables were only properly handled if their names
contained up to 8 characters.
The focus on support for 9 characters (rather than 10, 11, or more) in variable
names is justified by the fact that the code to parse Vtables, as well as the
intermediate file format, already support 9-character names.
* ungrib/9-char_varnam:
Use all 9 characters of namvar when printing field inventory in output() routine
Increase idlen from 8 to 9 in new_storage.F to support nine-character names
