Added Files:
	thesaurus_create.pl 
Log Message:
First, run updater/thesaurus_create.pl.
It creates a thesaurus table and fills it with data in bibliosubject. Thesaurus
contains 2 columns : freelib and stdlib. This permits connecting differents forms for a word/sentence (HUGO may be mapped to V. Hugo, Victor Hugo...)
In modbib.pl, you will see "..." near subject. If you   click on this ..., a popup appear. It has 4 parts : the Subject field, a search field with Search button. If you enter a value here and click Search, a list of thesaurus entries starting by what you enter appear.
If you select a value and click "OK", the value is added to the subject list.
When you've finished, click END. the window is closed, and the value copied to main subject window.

Make heavy use of javascript. TESTED UNDER MOZILLA 0.99. Please test under IE.

Administration of thesaurus table will come soon (with html::template) ...
