Add a new script to compile resources.

- No more dependency to reswrap binary (everything is done in python)
- Resource strings can be directly accessed.
  As side effect, it add a check at compilation if the resource is
  declared and compiled in the binary.
- The resource content can be overwritten at runtime with a env variable.

There is also few clean in the static as some files shoul be in the tools
directory.

The compile_resource script is install to let other project use it.
