client & MGR: Make writing trace statements to the debugger viewport something you have to opt into on Windows.

I use it a lot, but other developers using BOINC may not care to see BOINC messages while debugging their own stuff.
WINBUILD: Fix target file names for the screen saver and screen saver coordinator
lib: fix compiler warning introduced by commit ba84386.
MGR: Bug fix: correctly restore default task bar icons when switching from a different skin (e.g., GridRepublic) to default skin.
MGR: message tweak in new Diagnostics dialog; allow for branded application names.
MGR: fix a bug on Windows where clicking on a web sites button in Advanced View might cause the buttons to scroll without sending the button clicked event.
MGR: Fix typo in a comment.
vboxwrapper (Unix): make process_exists() work for non-children
Server: enable gzipped input files, and fix bugs in MD5 caching

The docs said that putting <gzip/> for a file in your input template
would cause it to be transferred in gzip form.
But most of the server-side implementation was missing.

- in process_input_template(), parse <gzip/>,
  and add <gzipped_url> elements to the output.
- stage_file was generating MD5 cache files containing only the MD5,
  but process_input_template() expected them to contain file size as well.
  Change stage_file to write both,
  and change process_input_template() to write an error message
  if it finds a bad MD5 file.
- remove stuff from process_input_template() related to
  "generated_locally", a feature that doesn't exist anymore.
