[Tutor] sig no matter what

The docs don't mention that case is immaterial for aliases, when it usually
matters in Python. The actual dictionary entries in aliases.py often differ
in case from the docs. For instance, this works:

>>> p = bytes("This sure sux", encoding="uTf32")
>>> p
b'\xff\xfe\x00\x00T\x00\x00\x00h\x00\x00\x00i\x00\x00\x00s\x00\x00\x00
\x00\x00\x00s\x00\x00\x00u\x00\x00\x00r\x00\x00\x00e\x00\x00\x00
\x00\x00\x00s\x00\x00\x00u\x00\x00\x00x\x00\x00\x00'
>>>

aliases.py
    # utf_8 codec
    'u8'                        : 'utf_8',
    'utf'                        : 'utf_8',
    'utf8'                      : 'utf_8',
    'utf8_ucs2'           : 'utf_8',
    'utf8_ucs4'           : 'utf_8',
    'ubom'                  : 'utf_8_sig'


So of course my favorite is u8 - less typing, and ubom for decoding if I
get those funny bytes ;')
