Extend eqdsk opts
Allow TTprime or q, as well as pprime or pressure as inputs when using an eqdsk file
Changed CHEASEgui as well
Check and fix NCSCAL=1 options when q profile is provided/known from eqdsk or IDS:
a) Either CSSPEC=0 or 1 can be used (with qin(0) or qin(edge)), hence csspec changed to 0 if csspec_namelist<=0.5, to 1 otherwise
b) Allow qspec to be specified from namelist at any csspec by specifying a qspec<0 (then abs(qspec) is used as qtarget(csspec))
