54942cf12e Less compatibility improvement 
If we get both a filename and a pipe, prefer the filename.

For example, this will show the contents of /etc/passwd:

$ echo hello | moar /etc/passwd

Before this change, it displayed "hello" on a page.

570d780bc2 NewReaderFromStream(): Make name mandatory 
This makes the API somewhat simpler to use. To support not providing any
name we still allow the empty string as the name, and document that
thoroughly.

ad767671eb Condition some log messages on --debug flag 
With this change, to get some log messages (about unsupported keys
mostly), you have to pass --debug on the command line.

Fixes #20

1fa52b9bc7 Use a global logger 
This saves us from a lot of passing-a-logger-around and makes the code
generally easier to read and to work with.
