Normalize more characters in font Unicode map

The previous patches were to fix searches.  This one should fix pdftotext
output.  For this document, poppler is just using the Unicode values from the
ToUnicode CMap, but acroread modifies or decomposes some of these characters,
so I guess poppler should too.

Attached patch moves the normalization pass to run after the CMap is read and
additionally normalizes some characters that I noticed acroread changes.  Some
greek letters, OE ligatures, and presentation forms blocks.

And all three patches should be applied, preferrably in this order:

Add Unicode mappings to gen-unicode-tables.py
Regenerate UnicodeDecompTables.h from gen-unicode-tables.py
Normalize more characters in font Unicode map
