This commit introduces a new plugin framework into the codebase of the
Mumble client. Note that "plugin" here really refers to a (more or less)
general purpose plugin and is therefore not to be confused with the
previously available positional data plugins (only responsible for
fetching positional data from a running game and passing that to
Mumble).
The plugin interface is written in C, removing the compiler-dependence
the old "plugins" had. Instead plugins can now be written in an
arbitrary language as long as that language is capable of being compiled
into a shared library and also being capable of being C-compatible.
As already indicated a plugin is essentially a shared library that
provides certain functions that allow Mumble to interface with it.
Inside Mumble the so-called PluginManager is responsible for managing
the plugins and relaying events to the respective callbacks. Plugins
themselves can also interact with Mumble on their own initiative by
using the provided API functions.

Apparently the first commit (59ae429972)
did not include all files.
Furthermore the used script tended to produce funny results in certain
cases. This has been fixed and as a result thereof a few more changes
were made in this second run.
* NULL plugins have a shortname of L"Retracted" which excludes them
from being listed as a plugin in Mumble >= 1.2.4
* NULL plugins are valid plugins that always return false on trylock
so Mumble <= 1.2.3 gets behavior close to what recent Mumble has.
* NULL css, dods, tf2 and hl2dm plugins as they have been replaced by link support in the source engine.
