Added some new schematron for common problems that arise after conversion that have to be fixed by hand, including when there is embedded verse in prose (which could be done programatically but is safer to do by hand to confirm lineation, etc) and other common errors (unescaped angle brackets et cetera). The idea here is that if the texts pass the basic TEI conversion (which they basically all do), the converter must then check the text and ensure that they are valid against the LEMDO schema; if not, then the texts must be modified slightly by hand to fix things that require human intervention. It's a bit more involved, but it stops absent minded conversion (which I am guilty of).

Fixed a ton of small issues (mostly embedded verse, but some other small things) and converted Mac and 1H4 as per JM.
