Put TopMenuStyle detection under a debug flag

[Veracity0]

Captain Scotch and others noticed that their "relay scripts" dropdown occasionally disappeared from their awesomemenu.

Since we only set topmenu style in three places:

1. MoonPhaseRequest
2. Visiting Interface tab in account.php
3. Changing menu style in account.php

this was confusing.

I inserted debug code to deduce the topmenu style from the responseText every time we decorated it to add the relay scripts dropdown.

Turns out that "visiting interface tab in account.php" was broken: KoL had changed the tag on the radio button, so if you had the "fancy" style selected, we'd think it was "normal".

With that fixed - and there are now extensive tests in AccountRequestTest - everything seems to be peachy.

Doing text searches to deduce menu style every time we decorate it is (again) no longer necessary.

I considered just ripping out that code, but I left it in under a debug conditional, controlled by debugTopMenuStyle, just in case we want to test with it in the future.
