Indicate Developer search

When the developer link wasn't included, prefix it with a search icon to
show that it's going to start a search instead of going directly to the
page.
Perhaps it would be better to show the search icon in the background or
use a different color text?
Standardize the "notes" property
Table: Use icons instead of bg for steam, desura

Was previously using background for the steam and desura links, but
testing by using onclick events is annoying. Also added titles to the
icons.
Bad developer links

Add titles to developer links, change color slightly for search links to
indicate they aren't direct links.
Tables: Add titles to reviews
URLs for all games thru Botanicula

Added steam/desura urls for some games even though they don't say they
come on steam/desura. Will find a way to invert icon or faded icon for
these links.
