External/wiiuse clean up, part 2. - More removal of unnecessary code - Windows: Modification of Wiiuse_Find under windows, instead of always deleting and recreating the whole wiimote_t struct, we do maintain the old one, adding/removing new wiimotes to/from it - some wiimote bugfixes, see below for details Windows related stuff: Fixed most of the disconnection issues (single and mulitple real wiimotes, both wiimote plugins) (I haven't had a disconnect msg in hours anymore(ms stack)). Rumble bug should be fixed now(both plugins,pls verify). Fixed some pair up issues( sometimes you had to press the pair up button up to 3 times, till it paired up your wiimote). More dongles might be now supported via ms stack, pls try and report back! Fixed a problem where multiple wiimotes would swap slots on pair-up/addition of a real wiimote (2-4 real wiimotes) (both plugins, but not integrated into new plugin). Improved ingame auto-pairup for real wiimotes(thx to the new wiiuse_find routine). Fixed a bug on setting wiimote timeouts, which means changing the timeout was just a dummy earlier. Most of the stuff concerns stuff in the old wiimote plugin, dont worry, in the end it's important for both plugins. It will get ported to the new plugin sooner or later.:') Some minor stuff. This might break osx/linux build and maybe the new plugin realwiimote-wise only. Thx to glennrics to pointing me to some breakings on linux, I didn't fix them all. PS I hope i haven't forgotten anything, enjoy. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5940 8ced0084-cf51-0410-be5f-012b33b47a6e
