Update gossip handling to store data in database and add new features

[sogladev]

Changes Proposed:

Update the gossip system to store data in the database instead of 2 large switch statements.

Add an index table that holds the hello gossip entries and specifies the action, allows configurable options for hello gossip such as setting an icon, description, level range, and mask (gear/talents/glyphs). Additionally, it allows re-usable talents/glyphs by specifying overrides.

Reduce the number of gear tables to one by using a race mask to handle human/horde/alliance gear.

Add an administrator command to create templates by exporting a character's talents, gear, and glyphs to the database.

Add lvl 70 T6 templates

Add instructions on how to add templates to the README. I wrote a tool, to help create templates, that generates GM commands from a wowsims config

Changes details:

• Store gossip data (hello and select) in the database instead of hardcoding with a switch statement
• Add an index table which holds the hello gossip entries and actions
• Allow configurable options for hello gossip, such as setting an icon, description, level range, and mask (gear/talents/glyphs), specific gear/talents/glyphs.
• Reduce the number of gear tables to one by using a race mask to handle human/horde/alliance gear
• Allow re-usable talents/glyphs by specifying overrides that allow them to be re-used.

• Refactor hardcoded strings to module_string
