Valknut/DCLib

This release mostly consists of bugfixes in both dclib and valknut. Note: this version will need to rehash your entire share to generate and store TTH leaves. This will create a large file in the .dc folder, similar to DC++'s HashData.dat. This version also changes the filenames for stored file lists.

DCLib was enhanced with more detailed logging. It
now supports ADCGet and TTHF for compatibility
with DC++ 0.696 and later. Valknut GUI was
improved to support new DCLib settings. Several
new commands were added, like custom chat
commands, a /sh command to send shell output, and
custom menu commands for the hub and the user
list.

Several miror bugs have been fixed, including a 100% CPU usage bug in OpenBSD 3.6. Apart from bugfixes, several smaller cosmetic additions have been added (search history, icons, and private chat rejoins).

Many code cleanups, slightly improving performance. There were also several small cosmetic changes, as well as bugfixes.

Several minor bugs were fixed in this version, including for a
problem with the asyncdns class, remembering the user list
width and column sizes, nick completion, the libxml API, and
wrong ports from dc++ search results.
