V0.7.5

Bugs Fixed

• If MathML is directly embedded inside of a MathML leaf element, it will be spoken well.
• Improved Chemistry so that if the intent property :chemical-formula is used, it is inherited and overrides heuristics to determine if something is a chemical formula. For example, "A=B" will now speak "=" as "double bond".
• Fix bug in German translation for division involving units (=> "pro")
• Fix bug in MathCAT dialog that prevented proper selection of Norwegian
• For ASCIIMath, added translations for chars with umlauts and also for ß (goes to "ss" because there is no defined encoding for it)
• Added literal speech for "‼" and "/" to English.
