moved deleteTables.sql to appropriate package

refactoring onrefactored DBAppender and DBAppenderBase to remove all mentions of classic concepts from core module

Added an option to the SocketAppender to call the getCallerData method on logging events before serializing them so that
the caller data is available on the remote machine.
Minor fix to SimpleSocketServer.java
Reformat only on SocketNode.java

This allows any event to decide the way it should look and any component to use the
same layout for that purpose.

Added an entry to codes.fml when filename is not set

modified css to display appender options

ongoing work on short intro

Fixed bug #27.

- added capability of setting collections of simple properties in PropertySetter and Joran
- small bug fix in Pattern class (a trailing / in the pattern string would cause the addition of an extra 
component with an empty string)

In BasicJoranTest, the method testTurboFilterWithStringList fails because Joran doesn't add correctly
users to the userList. Watch bug #27 for more info.

ConfigurationAction now pushes and pops the context to and from the objectStack, so that it is usable
by following actions.
Added an implementation of TurboFilter that allows debug level for selected users only.
Work in progress: the <user> element still makes Joran caugh a bit.

Other minor fixes

Still wondering if something better can be done, especially about the getActiveFileName method of RollingPolicy, that serves more
the purpose of a "makeInitialFileName" than just a getter to a value.

aligning method with the new name, i.e. TurboFilter
