Implement bbcode processing

[Redwyn]

I'm providing an update here for anyone who may be tracking progress on the client, I have gotten a partial implementation for a custom BBcode parser written. I did this in the span of a few hours so while it kind of works, it does not consistently detect tags and I haven't quite figured out why yet. Determining which tags are supposed to match up is determined by tracking depth (how many layers deep are we) and pairing up tags of the same type and depth.

Additional info:

• it will be possible to assign aliases for tags, aliases will be translated to a common tag identifier.
• the system at it's core will not include any premade tags. If you want to use a tag it will need to be manually defined. The reason for this is to keep the module lean and allow me to focus my full effort on making it functional/flexible.
• This may get it's own NPM module/repo but given my second bulletpoint the feature may not be large enough to warrant it.

Work is exhausting me now that I'm back from sick leave so I'll likely only be able to chip away at this little by little on the weekends. However, I am expecting to have this feature working before Wednesday if I can find the time.

I've worked out some issues with how the existing portion of the bbcode parser works, however I have gotten stuck at actually rebuilding the provided string with correct formatting.

This is still being worked on but could take me a bit longer than anticipated.
