Code review comment for lp:~j-corwin/openlp/migration

The openlpcnv.pyw is a hack at best, and the code from bible-1to2-converter.py is used in an online migration tool I am writing.

The reason the bible-1to2-converter.py script borks on Windows is because that module does not exist, and it requires a full edition of Visual C++ in order to compile (I tried it with the express edition, but it doesn't have one particular tool required in the linking process). I mostly created those two 1to2 scripts for our use as developers to easily convert 1.x stuff to 2.

Personally, I think that the online conversion tool should be the official upgrade tool, it would allow folks to upgrade without needing to install anything else on their computers. Of course folks are welcome to bring their own ideas to the table, but to me an online converter makes the most sense.
