Note to SylkServer users: hold your update until a new release of SylkServer is made, adapting to some API changes in the SDK.

Note to Debian Wheezy users: You need to have the wheezy-backports repository enabled because we depend on backported libav. Also, make sure you have libxml2_2.8.0+dfsg1-7+wheezy1 installed, since the newest available version in wheezy is broken.
