fix curl build on iphone, restore luaext features now that curl can work
untz mods for mingw support and restore webuntz for html host
remove blackberry build script and obsolete CI scripts
Added a default plugins cpp file (instead of just the .cpp.in to help with some build processes that might assume it exists
SDL host can now detect if it is in a bundle (osx app bundle) and run lua from its bundle folder via a bootstrap.lua file if it exists
XMLParser is an option dep but moai.lua assumed it exists and broke if it wasn't
misc extra includes for some of the ios files
remove moaibillingios from moai-ios folder, it has its own folder (same for storekitlistener)
Restored ios twitter plugin and playhaven plugins as full modules
commented out va_copy in zl_platform for MSVC since it is defined in vs2013 need to try a better fix for older Visual studios (although vs2013 is free now so why bother :))
reorganisation of cmake build scripts
 the moai lib is the star and is installed from the build scripts to be consumed by hand crafted (non-cmake) hosts
bin scripts have been updated to generate combined fat libs on iOS and moai.lib on windows for easier linking
desktop bin scripts also update the moai bin in util folder (if it is not already there)
ios cmake scripts have been broken up into modules and brought up to date
host templates to consume the prebuilt libs and moaiutil scripts to create the projects on demand from shared sources and libs
rejig android template to use src version of moaiactivity and moaiview
using src version of moaiactivity means you need bootstrap.lua so provide a default one that launches main
was pruned from my original branch, but seems I still need it to work. Mark build OS X scripts as executable
Added build instructions for CMake stuff and host templates on windows
correct windows docs
Merge pull request #1046 from moaiforge/pull-cmake-reorg2

Big cmake reorganisation and host templates
