Default instance name at startup

[PhillipsOwen]

this addresses an issue in #288 , #302

this is a implementation of getting/setting/resetting (via a UI data web-service) the default instance name to use when the app starts up. there are a number of things to test in this update as it spans:

• numerous aspects of the UI initial data gathering of map and control-panel data.
• the UI Data app that set/gets/resets the default startup instance name.

it also addresses bugs/tidying up in some other unrelated code discovered in testing. such as:

• improving the tool-tip text on the alert popup.
• not allowing geo-point selection whilst in compare mode.
• bug in adcirc-raster-layer.js when no product type is set for the current opacity setting.
• minor refactoring for code readability and comments.
