Third Beta Release

Various improvements and bug fixes.

- Made some code format consistency changes.
- Change: Filtering out minimum length phrases are no longer set to 3 as default and is instead disabled by default.
- New Feature: Filtering out numerics is now optional.
- Bug Fix: Regex pattern to split sentences was causing problems especially with sentences that have numbers in them. Changed to a simpler regex pattern.
- Change: Replaced `strlen()` with `mb_strlen()`.
- Change: Removed checks to see if `mb_*` functions exist as this library is dependant on PHP v.5.4.0 which will have those functions available.
