get rid of link between g2clib and g2lib, and just base g2clib in Application class; g2clib uses INC for include dirs, while g2lib uses INCDIR, so sharing make between them doesn't really make sense

split off function to path a Perl script to enable autoflush from wrf.py to filetools.py, and also use it for WPS

set environment variables using os.environ instead of os.putenv, fix logging in netCDF en var function

use netCDF env var functions, change 'wrfbuildtype' option to 'buildtype', add required custom make_module_req_guess and make_module_extra function definitions

add functions for setting netCDF environment variables, and generating module setenv commands for them

get rid of patch file that's not required, simply disabling usempi in toolkit options should suffice (if ifort is used as compiler, linker flags are set correctly)

significantly clean up determining correct build type, by used named group Q&A feature to construct answer based on matched question

correctly select WRF build type based on new toolkit_comp_family function in tools/toolkit.py; bring get_openmp_flags into Toolkit class so it can use toolkit_comp_family  as well
