Fix a crash on shutdown in kwallet if the wallet was never opened.

The wallet instance variable was not initialized so if the wallet was never opened we were trying to delete and invalid pointer.

Also update the dispose method of the provider to close the wallet as the
tasks in the queue hold a reference to the provider instance as the source
object in their tasks.

Testing Done:
Ran locally with both the kwallet and secret service providers.

SILC Purple Plugin
==================
This is the Purple protocol plugin of the protocol called Secure Internet
Live Conferencing (SILC). The implementation will use the SILC Toolkit,
freely available from the http://silcnet.org/ site, for the actual SILC
protocol implementation.
To include SILC into Purple, one needs to first compile and install
the SILC Toolkit. It is done as follows:
./configure
make
make install
This will compile shared libraries of the SILC Toolkit. If the --prefix
is not given to ./configure, the binaries are installed into the
/usr/local/silc directory.
Once the Toolkit is installed one needs to tell Purple's ./configure
script where the SILC Toolkit is located. It is done as simply as:
./configure
if pkg-config is installed in your system. If it is isn't it's done as:
./configure --with-silc-libs=/path/to/silc/lib
--with-silc-includes=/path/to/silc/include
If the SILC Toolkit cannot be found then the SILC protocol plugin will
not be compiled.
