Closes [LI-53] and nearly closes [LI-50] There is now an option in every tool's build.xml called hideTool, if set to true, the tool's valid flag will be set to 1 or 0 if false when the tool is deployed
Changes to build, so the tool deployer can put the tool_version in the deploy.xml when the tool is build. Now, the tool_version in tool_insert.sql must be replaced by @tool_version@, and the actual tool version goes in the buld.properties under tool.version
