Sonic Visualiser updated to v2.0 (incl. Mac 64-bit)

Sonic Visualiser has been updated to version 2.0 for Linux, Windows and Mac OS X. Despite the major version increment, this is a maintenance release.

Changes in Sonic Visualiser 2.0 since the previous release 1.9:

• Support 64-bit builds on OS/X (using CoreAudio instead of obsolete QuickTime audio file reader).
• Simplify RDF reading and fix some bugs. Now requires Dataquay rather than using Redland directly. Release builds use Sord/Serd rather than Redland.
• Add a fullscreen mode on the F11 key.
