Updated dependencies.

Support for brackets in MdC added. Now you can type in:

N17:i*(p:t)*(t:p)*i:N17

Databases are updated.
Now it supports numbers as ids. This means you cant type in

<sign id="500"/>

instead of typing

<v><h><sign id="V1"/><sign id="V1"/><sign id="V1"/></h><h><sign id="V1"/><sign id="V1"/></h></v>

This is the first release of the THOTH library.
