Debug|libgui: Commented out a debug message
Builder|Unix: Compiler log cleaner

The build logs contain a huge amount of non-interesting and repeated
information. This first version of the log cleaner applies to clang
and gcc and filters out the most important pieces of info (warnings
and errors), presenting a more readable summary.
Fixed|OS X|Shell: Missing include
Fixed|Builder: Recognize "g++" as a compiler in log cleanup
Fixed|Builder: Interpreting gcc build log output
Fixed|Builder: Counting words in log output

The issue counts were off due to false positives.
Fixed|Updater|libappfw: Showing the Updater notification icon

ProgressWidget in mini mode uses a zero color for the label's image,
so the Updater notification must use a separate label (it's cleaner
like this, anyway).
libdeng2|File: Don't return a reference to private member
Cleanup
libdeng2|Log: Keep track of the current log entry metadata

This information can be used by methods composing text for log
entries.
libdeng2|FS: Attempting to improve readability of file descriptions

A file description now adapts to the current log entry metadata in
that more verbosity is included for developer/verbose entries.

PackageFolder now describes itself as a "package" rather than
"folder."

test_archive now tests the three possible levels of file description
(with a PackageFolder and a NativeFile).
libdeng2|FS: Further clarified file descriptions

It is unnecessary to spell out "native" when it is clear that the
associated path is a native one.

FS2 paths are attributed as "path".
Fixed|GL|Client: Default value for 'vid-fsaa'

The value of console variable 'vid-fsaa' is persistently stored as
Config.window.fsaa, so it should get its default value from Config.
