Various minor changes:

• Added *.iml to gitignore as one doesn't commit the project files by accident
• Added new package names, so that the sources become more readable (attention: may require an update of local .idea/sourcegraph.xml definitions)
• Renamed some of the classes to make them easier to distinguish from other frameworks (Util -> SourcegraphUtil, Config -> SourcegraphConfig)
• Replaced log4j dependency in accordance with https://blog.jetbrains.com/platform/2022/02/removing-log4j-from-the-intellij-platform/
• Removed unused class imports from Search.java

Test plan

Rebuild and deploy locally - test in IDE. It should run as expected, however, as package names were added, the "repository" definition in .idea/sourcegraph.xml changed.
