Alpha v0.8.2

Lots of changes since the last alpha version, but key amongst the changes are:

• Support for JSP files. Note that this makes the assumption that Jasper is used on the servlet container.
• Reworking the sidebar in the trace details view to address some usability issues
• Huge performance improvements to the data handling
• Tweaked the appearance of the Treemap drawer to better fit into the rest of the column-based layout
• Changed the new trace creation workflow to be more responsive while processing the bytecode input
• Added a help box to show the java agent string to append to your startup command
