Improved reading of ENVI files

I had a hard time reading any of the ENVI files
from the ENVI demonstration CDROM into Spectral Python.

Attached are diffs towards Spectral/Io/Envi.py
which enabled me to read a file. It are patches
to obvious bugs in the code.

This worked for the first ENVI image which satisfied
the following criteria:
- data type == 1 or 2 (most seem to be 4)
- interleave != bsq (most seem to be bsq)

Also, the actual data does seem to have another
extension then .img. My solution was to copy the
header to a new place, and a soft linked called
<name>.img pointing to the actual data file.
