Remember what the Budget views looked like last time we were running

Browse Source 
Most of the work is delegated to GncTreeViewAccount, just as for 
GncPluginPageAccountTree.  One difference is that the Budget page has to
also remember which Budget it was showing.  For that, we encode the GUID to
a string in the keyfile.
