Update MenuFlags to work as expected

* 'popParent' has been removed
* 'noHistory' now works as expected
* Mods that explicitly want noHistory can state such in their constructor()

     * Routes for the file base now default to `/_f/` prefixed instead of just `/f/`. If `/f/` is in your `config.hjson` you are encouraged to update it!
     * Finally, the system will search for `index.html` and `index.htm` in that order, if another suitable route cannot be established.
 * CombatNet has shut down, so the module (`combatnet.js`) has been removed.
+* The Menu Flag `popParent` has been removed and `noHistory` has been updated to work as expected. In general things should "Just Work", but check your `menu.hjson` entries if you see menu stack issues.

 | Flag | Description |
 |------|-------------|
-| `noHistory` | Prevents the menu from remaining in the menu stack / history. When this flag is set, when the **next** menu falls back, this menu will be skipped and the previous menu again displayed instead. Example: menuA -> menuB(noHistory) -> menuC: Exiting menuC returns the user to menuA. |
+| `noHistory` | When leaving the current menu to load/chain to another, remove this menu from history. In other words, the fallback from the next menu would *not* be this one, but the previous. |
-| `popParent` | When *this* menu is exited, fall back beyond the parent as well. Often used in combination with `noHistory`. |
+| `mergeFlags` | Generally used in code only: Request that any flags from `menu.hjson` |
-| `forwardArgs` | If set, when the next menu is entered, forward any `extraArgs` arguments to *this* menu on to it. |
+| `forwardArgs` | Forward this menu's `extraArgs` to the next. |
+
+> 💡 In JavaScript code, `MenuFlags` from `menu_module.js` contains constants for these flags.
