Basic Team Storage

[kenedos]

What this PR Adds:

• Basic implementation of Team Storage
• Items in team storage are shared among characters in same account
• Allows for storing and retrieving silver
• Allows for purchasing team storage expansions with silver (up to 9 - limited by client)
• Allows user to set custom default sizes of team storage (up to 70 - limited by client)
• Minimal necessary changes for WebServer so client does not show errors when opening team storage
• Checks for player level to open team storage

What this PR does NOT add:

• Purchasing 'additional tabs' on team storage, a.k.a. these buttons:

• Expanding team storage via special premium items, such as tokens, collections, etc.

• Custom client injections to allow for more than 9 team storage expansions using silver

• Fix for team storage failing to open (e.g. due to player level) and then the NPC becoming untakable. This happens due dialogs not closing properly (bug in melia - PR #348 fixes it.)
