Ops Console v0.2

Updated the Ops Console to v0.2 and added some new features

1. Removed previously obsoleted PowerShell wrappers around galops
2. Removed need for separate environment PowerShell scripts, now the environment data is retrieved from Azure on-demand (it can be provided as the -ConfigFile argument to galops.exe if the Azure Management API is down for some reason)
3. Instead of \\nuget\Environments\*.ps1, an Environments.xml file is used to describe each environment (see Environments.sample.xml)
4. All tasks have been updated to use the data from the Config File instead of Environment variables as the defaults.
5. Added WarehouseTask base class for tasks which need a connection string to the warehouse
