[Lint] Convert all python double quotes to single quotes

 * A rather disruptive change but for a few reasons such as easier to read,
   easier type, keep consistent and javascript code uses single quotes.
 * There are a few exceptions for the automated process:
    * Any double quotes in comments
    * Triple double quotes for docstrings
    * Strings containing single quotes are left e.g. "they're"

 * To deal with merge conflicts from feature branches it is best to follow
   these steps for each commit:
     * Create a patch: `git format-patch -1 <sha1>`
     * Edit the patch and replace double quotes with single except those in
       comments or strings containing an unescaped apostrophe.
     * Check the patch `git apply --check <patchfile>` and fix any remaining
       issues if it outputs an error.
     * Apply the patch `git am < <patchfile>`
