Diggy: add blueprint tools

[RedRafe]

This PR adds Blueprint tools for Diggy scenario.

Context & feature explanation

Support beams (tiles and special entities) cannot be marked for deconstruction by default (antigrief/safety feature)
Regulars and above will have access to this new feature to turn On/Off the safety measure however they prefer.
The feature will automatically popup whenever the player is about to perform a "blueprint action", which is:

• using a blueprint record
• using a blueprint book
• setting up a blueprint from map
• holding a blueprintable item-entity in hand

Players can:

• turn On/Off the safety measure all together
• turn On/Off tiles in bulk
• Show/Hide the popup window (from this window or RedMew "Settings > Show blueprint tools")
• turn On/Off individual entities

Here's a quick demo that goes through the various settings/cases:

Changes:

• moved support beams definition from presets to template
• moved on_marked_for_deconstruction handler from diggy_cave_collapse to BP Tool module
• BP Tool is now responsible for the antigrief feature all together

Arguably, diggy_cave_collapse module could force require this module or I could have included this logic in diggy_cave_collapse to begin with, but I thought if would have been cleaner to detach the antigrief/tool logic on its own module as it handles a lot of Gui events rather than game actions.

I solved the edge case of demotion with player still being able to still decon stuff, fixed it and tested it again.

I also implemented a quick admin GUI /blueprint-tools that lists all the players' settings and can act as a master toggle for them (per-entity mask is included as well, On/Off switch should be enough to quiet any doubt) .

This command is available to Moderators+ as per new rank system

From MP game (obviously everything is On since nobody hasnt played with it yet)
