John Willard c58cbb4dfb Reworked PDA menu & NtOS themes (#73070)
## About The Pull Request

This is a port/rework of
https://github.com/yogstation13/Yogstation/pull/15735 - I changed a lot
of how it acted (some themes are locked behind maintenance apps).

The original author allowed this port to happen, and I really liked how
it looked there so I'd like to add it here.

### Applications

Removes the hardware configurator application, as all it did was show
you your space and battery now that all hardware was removed. These are
things your PC does by default, so it was just a waste of space.
Adds a Theme manager application instead, which allows you to change
your PDA's theme at will.
Adds a new Maintenance application that will give a new theme, however
it will also increase the size of the theme manager app itself as it's
bloatware.

### Menu

There's now a bar at the top of the menu showing 'special' tablet apps
which, for one reason or another, should stand out from the rest of the
apps. Currently this is PDA messenger and the Theme manager

Flashlight and Flashlight color is now only an icon, and is shown on the
same line as Updating you ID

### Themes

Adds a lot of themes to choose from, although SOME are hidden behind
Maintenance applications, which will give you a random theme. These are
bloatware however, so they come with some extra cost to the app's
required space storage.

Themes are now supported on ALL APPLICATIONS! If you have a computer
theme, you will have that theme in EVERY app you enter, rather than just
a select few.
ALSO also, emagging the tablet will automatically set & unlock the
Syndicate theme, which makes your PDA obvious but you can disguise it if
you wish through just re-painting it to something else.

### Preferences

This also adds a pref for theme, reworking the ringtone code to work
with it as well. I also removed 2 entirely unused PDA prefs just 'cause.

Screenshot not up-to-date, they now have proper names.

### Other stuff

Made defines for device_themes
Added support for special app-side checks to download files
Fixed programs downloading themselves TWICE because defines all had the
same definition
Removes the Chemistry computer disk as it was empty due to chemistry
app's removal
Removes the 'run_emag' proc, since apps can directly refer to the
computer to check for emag status instead.
Moved over and added better documentation on data computer files, and
moved the ordnance ones to the same file as the others.

## Why It's Good For The Game

It makes PDAs a lot more customizable while adding more features to
maintenance applications. I think the themes look cool and it fits with
PDAs being "personal" anyways.

I also explained most of my other arguments in the about section, such
as the hardware configuration application.

## Changelog

🆑 Chubbygummibear & JohnFulpWillard
add: A ton of new NtOS themes, which are accessible by the new Themify
