Replace all occurrences of `M.require( 'mobile.startup/pathToModule' )`
with `M.require( 'mobile.startup' ).pathToModule`. Where multiple
requires existed, add an intermediate variable,
`var mobile = M.require( 'mobile.startup' )`, and dot off that.
This changes improves the consistency of MinervaNeue which currently
contains a mix of require styles and eliminates any deprecated requires.
