Split the functionality into several different source files. Reorganized the
architecture of the whole package.  Splitted readme.js into main.js (which
is module-independent) and silabeo.js, palabreo.js, and lectura.js (which
are dependent on each module.)
Removed symbolic links to jquery css and js files, put the same links within the corresponding folders.
Changed the name of js variable from sounds to syllables.
