Description of the new feature/enhancement

The current quake mode implementation entails a window with a well-known name. This window gets specially handled with regard to summoning: it gets docked and focus mode is turned on. It is otherwise a normal window capable of hosting multiple tabs.

There are existing requests filed for supporting multiple quake mode windows, each with a different profile running. That seems unnecessary given the ability for an existing terminal window to host multiple profiles already. What is lacking is the ability to specify which tab to bring active on summon.

Proposed technical implementation details (optional)

Allow the ability to define reserved tabs by name:

"windows": [
  {
    "name": "_quake",
    "tabs": [
      { "profile": "<guid or name .. not sure which would be better>", "name": "my PS tab" },
      { "profile": "...", "name": "my scratchpad tab" },
      { "profile": "...", "name": "my wolfram tab 1" },
      { "profile": "...", "name": "my wolfram tab 2" },
      { "profile": "...", "name": "org mode" },
      { "profile": "...", "name": "dashboard" }
    ]
  }
]

or, alternatively, add "window" and "tab" names to the existing profile schema, binding them exclusively:

{
    "guid": "{61c54bbd-c2c6-5271-96e7-009a87ff44bf}",
    "hidden": true,
    "name": "PowerShell",
    "window": "_quake",
    "tab": "my PS tab"
}

Then add an argument to wt.exe that allows specification of the specific tab name to activate (or, if the alternative approach is taken, a profile which has a window and tab name defined). If it is not already live, it will be activated. In this way, hot keys can be defined to summon specific tabs.

On exit or close of any of the named tabs, the tab will remain open, waiting to restart the command in question (immediately, if currently active).

Additional tabs created in the window will follow after the named tabs.
