- specify -Dmacro on the builder command line to automatically include the macro in the compiler command line
- refactoring: option handling code now moved to utils/utils.lua
- various small bugfixes
The files that will be compiled to link an eLua image are now found automatically,
there's no need to specify them explicitly anymore. This applies only to the main
'build_elua.lua' build file, each target's 'conf.lua' still needs to specify them
explicitly (but can use the same automatic source file finding as the main build file).
Added a 'summary' display mode in the builder which displays less information
(thus making the output more readable) and also adds colors :) Not exactly
very useful but I saw this recently in cmake and I _had_ to implement it :)
Activate with "disp_mode=summary" in the command line.
Now a target can be reffered to also by its name, not only by the
corresponding _target object. Also added 'utils.lua' as a separate
file in utils/ (it used to be a part of build.lua)
