Improved project searching

In the new changes to Jarvana that should be going out in the next week, project searching in Jarvana has been improved to accept things such as spaces and the names of jar files in addition to the older groupId/artifactId querying. In addition, I made some updates to wildcard project querying so that certain types of queries now happen in under a second rather than taking several seconds. These updates should be a big win in terms of usability.
