Update messageformat.dev.js to 0.1.5

This file had not been updated yet, however it shall be the reference
for the developpement (rather than the messageformat.js root file).

This branch is little work on the publishing process, to avoid any
mismatch like this.
Enhance publishing with Makefile

Add new targets *make parser* and a *make publish* in the Makefile.

- __make parser__ verify the presence of pegjs then call it to compile
the rules specified in *./lib/message_parser.pegjs* to the
*./lib/message_parser.js* file

- __make publish__ depends on the target described above, and generate
the ./messageformat.js root file, required by browsers.

This chain is intended to save time and avoir any conflicted version
between the development stuff and the production build.
