Availability zone check

Now the application checks if the account where the reserved instance is has access to the destination availability zones.

Performance improvement

Now all the summary and recommendations are cached in the database. You can define in the setup the period of time to refresh the information using the API calls.

New version with major changes

Now I've removed the Rails cache, and the Database is updated every 5 minutes with the information from the accounts.

You can select an option to give priority to the account where the RI was purchased when selecting instances to match.

Now the tool is able to join RIs of smaller instance types into one bigger.
