Added EvalMath library to COPYRIGHT.
As requested by @rdoursenaud

Actual library update has been done at a3a5b0d9

This is nusoap dependency and the unkown previous version
was GPL incompatible and used deprecated functions.

Contain FPDF_TPL natively

into function multipleselectarray (except loading of css).
Code is prepared to choose which plugin to use (only a if is required
to switch or add a new manager). Introduce working version with
multiple-select jquery plugin. Removed deprecated old jquery plugin.

Includes important fixes for PHP 5

plugins should use minified version).

Qual: Removed not used library.
Look: Uniformize css.

upgrade were not yet received. So we prepare for GPL by uniformizing
licence text keys to GPL-3+. Will move later to AGPL if all answers are
positive.
