How-to-cite uses non-capitalised Monasterium.net name

[GVogeler]

The How-to-cite-section in cei2thml.xsl should use the conventional naming of Monasterium.net with a capitalized 'M' at the beginning.

This seems to come out of charter.widget, my-charter.widget, and saved-charter.widget. I've also found the non-capitalized spelling in notes2pdf and cei2pdf - I'll include all of these in the fix.
