Upgraded Restlet, switched logging to log4j.

Using Restlet version 2.1.6 now instead of 2.0.0, resulting in a
significant performance increase in some tests. Logging is switched to
log4j. Restlet logging goes to log4j by way of slf4j. Also, fixed an
issue in which "localhost" was hard-coded as node address.
Merging changes to MATLAB files to files in matlab-files

Of course!
Now "http://" will not be required in addresses.
Clarified warning when published variable value is not cached.

When a variable is first published, it's value is not yet cached in
LAPIS. There is a warning when the value is retrieved from LAPISData and
not found in the cache. This is normal when the variable is first
published, so I clarified that in the warning.
Removed eclipse files from source control.

Removed .classpath and .project files.
