- "building" page completely rewritten
- a new page about the toolchains used in eLua
- a graphical representation of the system architecture (doc/wb_img/elua_arch.png) that will be used in a soon to come page about the eLua architecture
Also:
- validate.h updated with some new tests (still needs more work)
- "arm-gcc-eabi" toolchain name changed to "codesourcery", since this is obviously way more intuitive :)
