[Erikos66]

What Does This PR Do

Adds a portal tool to build mode, allowing the user to create portals.

Through the settings you can customize, appearance, behaviour and duration.

adds a new icon to buildmode.dmi;

Why It's Good For The Game

Having a more RP friendly way than the jarring GET or SEND is good, it may also prove useful during certain events.

Testing

Tested on a local server, appears to work as intended.

Here are some videos of the portal mode in action;

Actually after some testing in game during the TM, there are a few things that need to be adjusted. I am going to review this properly, but I am throwing up a change request to prevent accidental merge.

[Erikos66]

Following fixes and changes were made per request;

• Can now clear setting the destination by right clicking
• Should report lifetime correctly at-least does on local
• Exiting the settings no longer requires you to sit through the rest
• Arbitrary 500 second limit was silly, swapped out for an arbitrary 999 second limit
• Quick create portals no longer lands you in dense objects

[Erikos66]

Changed up a lot of things + new features, hopefully it should be easier to understand;

• Portal preview only visible to the owning client when selecting origin (Can also see where you clicked now)
• Alt + click now deletes portals
• Summary is hopefully easier to understand
• Broken some things down into procs for readability

Probably the last additions ill be making, feedback is very welcome however.
