LDEV-2823: Add properties that select whether standalone or embedded MySQL should be used for LAMS run and/or build. Make all Tools use MXJ connectors if needed. Make Tool Deployer usage lighter - libraries are not copied to Tools but they are referenced from a single spot. Copy MXJ connectors from "mysql_embedded" project if needed.
LDEV-2737: Change Tools' web.xml files to comply with LAMS 2.4 Tool Application Context discovery mechanism. Add missing abstract methods implementation. Remove several libraries as they interfere with endorsed XML libraries on JBoss 5.
