Remove ActiveSupport dependency

This commit removes the dependency on the `ActiveSupport` gem by doing
the following:

- Replace `constantize` with `Object.const_get()`
- Remove the following `Object` methods:
    - `blank?`
    - `present?`
- Remove the following `String` methods:
    - `camelcase`
    - `titleize`
    - `underscore`

Closes kslazarev#106
