improving detection of MathML

This is my final version of the patch. It has this goals:

Make it possible to open and import MathML fragments, which have only the math
element body. That makes it easier for users to reuse formulas from external
libraries.

Make it possible to open and import MathML files with any prefix on the math
element. OOo1.15 had used prefix "math", MS Office uses prefix "mml", other
prefixes are possible.

Detect MathML files, which are UTF-16 encoded. The MS Math Input Panel puts
such files into the clipboard.

The patch tries to open all files in Math, which the parser can parse in Math
context. If you find a file, that will be detected as "MathML", but the parser
is not able to open, inform me and attach the file. Such case would result in
an "General input/output error".
