WebNetCPU (index.html) changes (re-styling, bugfixes, etc).

GUI restyling, inclusive of: fonts, color schemes, border adjustments, animation, etc.; added waiting_animation to the 'processing please wait' status when reloading the tasks-list; also shortened the debug textual output for the active task (the suggestion to not reload/refresh contents all the time, should be rather implicitly common-sense really... esp. with the increasing user-experience in interacting with the software).

Bugfix in the context menu: 'cancel' button did not work ('this.hide' was wrongly referenced, probably from the days when 'this' was passed around via the 'pid' thingies); also a bugfix w.r.t. populating "down the column" option from the context-menu (in the additional-complexities table) was referencing a typo (non-existing field).

Minor coding impromevements (almost syntatic -- taking out redundant variables, making some into a 'static' scope, etc. nothing much or comprehensive... a lot more ought to follow in future).
Server.cc et al bug-fixes and minor feature additions...

Untested new ability to save convergence state when pending task is moved in the waiting queue (required reworking from ::boost:: scoped_ptr to the ::censoc::unique_ptr interface when deactivating a task due to the possibilty of double-delete, recursive chain-reaction call).

Bugfix w.r.t. moving tasks (in queue) was rather broken (w.r.t. multiple use-cases), should be cleaner now.

Bugfix w.r.t. end_process_writer, potentially, leaving the io_driver in the unclean state (multiple 'good' messages queued up and being incorrectly taken as a reply to the sent 'end_process' message... whereas, in reality, they were just responses to the previous objects' messages)... now the server (end_process_writer) is expecting 'end_process' to be echoed back from the client (as opposed to a generic 'good' being echoed) before passing control on to the peer_connection object.
