Enhancements

• memory collector for exposing more information about memory usage (#266, thanks @aswhit1!)
• We now have documentation for all the collectors in the docs/ directory. Help with extending the info around practical usages would be very appreciated! (#113)

Bug fixes

• The textfile collector now handles different Unicode byte order markers (BOMs) that may be present from some tools (such as Powershell). (#285, thanks @hairyhenderson)
