* Added StringUtils with string hash functions.
* Added Locatable{Entry,File,Directory} and FileManager classes to manage the
mapping from debug info/target file names to local file names.
* Image does now have a LocatableFile referring to the image's shared object
file. Added listening to location changes of these files to TeamDebugger. No
action is taken yet (should trigger reloading the debug info).
