jslint: fix type confusion and property access

fix various type confusion, for example:
items: {} and items: []
style: string and style: {}

also fix object['property'] access with
object.property

also fix /=/ with either '=' or /\=/ where appropriate
(/=/ can be confused with /= according to jslint)
