input files must be checked on content, not file extension

[GoogleCodeExporter]

nx_util checks only the file extension when importing from logfiles. This is 
not the best thing to do because a file with extension .gz (or .bz2 in the 
future) is not necessarily a gzip compressed file.
I'd check in a manner similar to the "file" command.

Hello,

I added support for bz2 files (in trunk)
However, I do think that it's somehow best to rely on file extensions, 
as this something quite predictable, so far extensions .bz2 and .gz are 
supported, would you see any other to add ?

Hmmm, maybe .xz / .lzma / .7z are candidates ? But I doubt they're commonly 
used.
