Tab dropdown

[bushwallyta271828]

Current things to fix before merging:

• I need to add a definitionClaimID input box to the "Attach Definition" item and generally figure out the UI for that process.
• I need to fix the width of the tab dropdown menu.
• I need to make the tab expand to fill the height of the claim.
• I need to fix the depths of the various objects so that the claim tabs don't appear above other menus.
• I need to make the claim tabs draggable.
• I need to implement the attachDefinition and deleteClaim state management functions.
• I need to use those state management functions in the dropdown menu.
• I need to create warning pages before the user can delete a claim.
• I need to create a dropdown menu for the definition tabs that allows for deleting tabs.
• I need to create a state management function removeDefinitionAttachment.
• I need to tie removeDefinitionAttachment to the definition tab dropdown menu.
• I need to make sure that the new definition tabs are still draggable.
• I should create new custom colors for dangerous actions and tie them to "Delete Claim" and the remove definition attachment button.

Another bug:

• I don't think that the body is extending all the way down the screen for large screen sizes.

The depth issue has been solved at the expense of the claim tab dropdown appearing on top of the claim tab itself.
