Store names as UTF-8

The names should be always in UTF-8 encoding. At least for PostgreSQL
the encdoding of the database comes from the time of running 'initdb'
(which is different from 'createdb') and if the encoding was selected or
set to something else at that time, the following error will occur:

  File ".../pyfpdb/Database.py", line 1630, in <lambda>
    self.pcache = LambdaDict(lambda  key:self.insertPlayer(key, siteid))
  File ".../pyfpdb/Database.py", line 1661, in insertPlayer
    c.execute (q, (site_id, _name))
  File "/usr/lib/python2.5/encodings/iso8859_15.py", line 12, in encode
    return codecs.charmap_encode(input,errors,encoding_table)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u2122' in
position 10: character maps to <undefined>

This happens because 'name' is a regular string as opposed to a valid
unicode object. By forcing the string to unicode and encoding it in
UTF-8 the error goes away. In my case the database encoding was
ISO-8859-15 (latin9) but any other "wrong" encoding would trigger the
same problem.

This is a relatively common problem in python.
