also fixed a save_restore issue with grid alignments
now save_restoreGB() saves/restores offset values
added macro enumeration of SAVE vs RESTORE for save_restore commands.
add demod data to graph.
some bugs are known:
if you close the graph window data plot will not bring it back.
exiting the application without closing the widget form results in
error.
autocorrect graph y labels are ugly
form has old askdemod tab.
sticky button purpose not defined/labeled well.
doesn't clear s_Buff when new graph loaded or sampled.
probably more...
