Added Tremor Ogg decoder, removed libvorbis from Makefile. OGG audio working perfectly.

Browse source 
Tremor is extremly similar to libogg but only uses integers (and doesn't provide an encoder). The playing problem with libvorbis was probably a float-precision related issue.

No need for make build-all.

<H1>Setup/Teardown</h1> <p>In order to decode audio using
libvorbisidec, a bitstream containing Vorbis audio must be properly
initialized before decoding and cleared when decoding is finished.
The simplest possible case is to use <tt>fopen()</tt> to open a Vorbis
file and then pass the <tt>FILE *</tt> to an <a
href="ov_open.html">ov_open()</a> call. A successful <a
href="return.html">return code</a> from <a
href="ov_open.html">ov_open()</a> indicates the file is ready for use.
Once the file is no longer needed, <a
href="ov_clear.html">ov_clear()</a> is used to close the file and
deallocate decoding resources. </b>Do not</b> call <tt>fclose()</tt> on the
file; libvorbisidec does this in the <a
href="ov_clear.html">ov_clear()</a> call.
<p>
All libvorbisidec initialization and deallocation routines are declared in "ivorbisfile.h".
