Code review comment for lp://staging/~jconti/indicator-applet/gnome3

I unfortunately converted the tabs to spaces in src/applet-main.c, which makes the diff kind of ugly, so I did the same with Ted's branch and posted a slightly better diff here: http://paste.ubuntu.com/725607/

It is worth noting that I took a look at Ted's branch after seeing the merge proposal, and it appears to work correctly with just the updated configure.ac, data/Makefile.am and src/tomboykeybinder.c (to silence a warning) from my branch, so that may be another way to go since I made quite a few possibly unwelcomed changes in my branch (such as using the logging functions from lightdm, since I found that the ones in indicator-applet tend to lose debug messages occasionally).
