#100 Italicised sigla in Latin (non-standard)

[BODARD Gabriel]

John Bodel:
"In guidelines for erasure of text in antiquity (and elsewhere).: the xslt output of brackets and any editorial text within them (e.g. 'vac. c. 5') should be in Roman rather than italic (as, e.g. correctly in the description of [ ])."

[Tom Elliott]

Needs checking across Guidelines and XSLT

[Elli Mylonas]

Guidelines seem to have text in Roman, not italic. See:
- http://www.stoa.org/epidoc/gl/latest/trans-erased.html
- http://www.stoa.org/epidoc/gl/latest/trans-erasedillegible.html
- http://www.stoa.org/epidoc/gl/latest/trans-erasedlost.html

In the second example, there is something that looks italic, but it's probably my browser's Greek display.

Double checked that it's been fixed
