Ability to specify where a MAPPING tag should be added in the tag_list

Tags in vislcg3 are "unordered", but the input order is preserved, and MAPPING tags are added to the end. However, since Apertium matches longest left-to-right strings, we may have to disambiguate between ganga# i<vblex> and ganga<vblex>+i<pr>. The first one is easy, "ganga# i" is seen as the baseform and there is just one tag, vblex, we might get something like ganga# i<vblex><@FVMAIN>. The second one is worse. The + means that the multiword should be split into two before transfer, ^ganga<vblex>$ ^i<pr>$; but if the mapping tags go to the end, or even after the first word, we'll get ^ganga<vblex><@FVMAIN><@PART>+i<pr>$ or ^ganga<vblex>+i<pr><@FVMAIN><@PART>$, but we want ^ganga<vblex><@FVMAIN>+i<pr><@PART>$.

CG Syntax change: We could say something like

MAP (@FVMAIN) TARGET VPart:0 (1* FOO);
MAP (@PART) TARGET VPart:1 (-1* BAR);

This is better done using Subreadings.
