Updated some typos in Readme and changed some things
Removed max:1024 characters from note field validation since we're using medium editor now. Lots of html.
Minor refactor, dependency clarification, and adds method doc blocks

- Extracts instances of `\Class` to `use Class`;
- Consolidates `find()`
- Adds possible TODOs via `@todo`
- Removes `Str` facade in favor of `str_random()` helper method
- Clarifies what is being returned from functions
    - `delete()` was not returning anything
    - Clarifies reason for assumed success on `deleteNotesOlderThan()`
- Whitespace/Alignment
Removes `composer.lock` from `.gitignore` - Updates `composer.json`

- Updates Laravel to `"laravel/framework": "4.2.*"`
- No `composer.lock` file presently being tracked
- The current `way/database` requires 4.2+ ... didn't see any other choice
- `phpunit` still passing ... means nothing else is broken right?! ;)
