addtrisoup_simple now supports line lists too. fix a memory leak in the sound code. fix chunked http download corruption in certain cases. reworked the networking associated with entity editing. now carries ids instead of indexes (qc isn't aware of them). 'map blarg.map' will now auto-create a dummy map if it does not already exist. this should make it easier to get started with map editing. fix some issues with banning yourself - loopback can now mute etc themselves, but not ban themselves. downloads/updates menu now handles plugin detection. user-installed plugins will result in a prompt allowing the user to enable/disable/delete them. This makes using plugins more explicit. revamped help menu to remove m_state fix silly ode copypasta bug, added preliminary bullet code in case anyone is interested. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5090 fc73d0e0-1445-4013-8a0c-d673dee63da5
