Skipping Proofreading / typos for string blocks.

I'm trying to do some code cleanup and have been playing with the Code Inspection feature and have run into an issue, which may be edge case for our useage.

We have a Vue.js front-end running against a Hapi.js backend which talks to a mySQL database.

Our database backend has it's field names defined as `prefix underscore name` so would be something like `tb_fieldname`
This naming convention triggers the type on the spellcheck as it expects it to be `tb_fieldName`

We don't want to disable camel-case checking as for the Vue front-end camelcase should be properly respected and the typo check has been useful.

But we would like to skip typo checking on the query definitions such as:

sql = 'SELECT tb_fieldname1, tb_fieldname2\n' +
   'FROM tablename\n' +
  'WHERE tb_fieldname3 = ?\n'

I have tried to turn off checking on `process literals` but this hasn't worked
