assistance with dbseo vbet rewrite rules

[Marcin Kalak]

Integration vBSEO with vBET works by replacing vBSEO functions on vBET functions. See: do-not-upload/readme.html->Integration with other mods->vBSEO Integration. Functions vBET translate text and parse it properly (using vBSEO functions) and return it. These functions are contained in file: upload/includes/vbenterprisetranslator_functions_vbseo.php. This file are included in hook: init_startup. In addition vBET sets some variables vBSEO accordingly.
