Add annovar protocol

[patmagee]

Each annotation has a specific usage protocol that needs to be included when you do the page configuration. ie. g or f

When you submit the config page a separate array should be added that contains this information

[patmagee]

The new attribute should be named:

'annovar-usage'

and point to an array of == length as the 'annovar-dbs' array.

Additionally I forgot to mention that refgene should be included in the annotations!
