Initial implementation of the modeshape teiid sql sequencer

* This sequencer parser is generated from the teiid client's version of
  teiid's javacc template.

* The nodes will be initially generated then committed to wrap modeshape
  AST nodes and the setters used to populate the children and properties
  of these AST nodes.
Adds the jcr-api library to the modeshape library plugin

* Constants actually used by the ddl sequencer and soon by the teiid sql
  sequencer
Updates the target platform and fixes library plugins

* Respin in locus update site updates qualifiers of plugins so target file
  must be updated accordingly. Updated again when new integration-stack
  spin is released to maven

* Build files should still depend in target platform installation
