enabled ssl support in windows for plugins. updated jabber plugin. tweaked downloading logic in an effort to end the madness. Updated sql code to support sleeping the qc thread until query completion, as a more readable alternative to callbacks. Client updates should be more explicit now, removing a potential bug. networked terrain editing should now be in a better state. updated the dir command to show paths too (so when the same file is listed twice, the pak its in will at least be different). Many files changed because of this. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4273 fc73d0e0-1445-4013-8a0c-d673dee63da5
