Release 7.3.1

JSesh 7.3.1 is out !

It's somehow a small bug fix for 7.2. It should be a bit more consistent regarding copy/paste size. The main feature,if you have difficulties with copy/paste and word using Windows, is that EMF copy/paste will be now marginless, which is better when mixing glyphs with texts.

Besides, the default embedded format for RTF graphics is now EMF. It might suffice to solve many problems.
