Provide separate libraries for LGPL components

Ember uses a number of Ogre related components that are licensed under the LGPL. Amongst these are Caelum and the PLSM. These are provided with the Ember source since a) they are not very stable yet b) I've made some changes to them to get them to work better with Ember. They are however statically linked into the main Ember compilation, and therefore relicensed as GPL, as required by the GPL and allowed through section 4 of the LGPL.
I would however very much rather respect the original LGPL license as chosen by the authors of these components. In order for that to work they must compiled, installed and loaded as third party plugins. This isn't so hard to do since they originally are designed for such purposes, but it requires some changes to how they now work within the Ember system. There's no need to provide them in a separate source package, as long as they are detachable from the main Ember code (i.e. in a sole subdirectory). But they must be compiled as .so or .dll files and loaded dynamically at runtime.
