fixed events presentation
fixed management-server alias force overwrite error message bug
disabled reinitalization of an already initialized directory
fixed init method, added protection against non-existent target directory
added protection for errors in provider calls
fixed bug where 'cloudify_<PROVIDER>' value would fail, as well as added exception handling for ImportErrors for Provider modules in general; Init target dir param is now processed by expanduser; if Init fails on Provider (or in provider code) it will no longer leave the .cloudify file in the target directory; improved error handling on exceptions thrown from Providers
changed requests's urllib3.connectionpool logger level to ERROR, so blueprints upload command will no longer show a useless warning
added protection for non-existant paths for blueprint upload, and also now processing the path through expanduser
