Generate HMAC signature for API request

In OTM2, most API requests need to have an X-Signature header
added which is modeled after Amazon SimpleDB api request signing [1]

This class generates the signature in the same fashion that the server
will be checking against request values.

Update login endpoint to user

/login has been renamed /user as it reflects the actual utility,
since it returns user info, and does not actually 'log in'

Make Username default focus on login

Password was always the default textbox, which is terrible.
Fixes to enable profile page display

edits so we are skipping this feature presently.

Fix Profile page
Rename "App" Instane to AppInstance

The OTM1 version of this project referred to the global App
context as "Instance", but in OTM2, "Instance" refers to a
created tree map.  To avoid confusion, this existing term and
its associated methods have been renamed to AppInstance
Request configured Instance info

When an instnace name is supplied with the initial configuration
the app will attempt to retrieve information on that instance
immediately.
Update plot display from map tap

Copying the iOS version, I've removed dbh and last updated
from the tree info, and am now using the title property from
plot instead of species directly.  Begining to comment out
filter generation code which is broken for now.
Display plot details

Updates to conform to the OTM2 structure for plot/tree/species
