[TPHD] Add bloom graphic pack

[KoB-Kirito]

Inspired by the work of @skalfate - #508 (comment)

I tinkered a lot with the values, tested them in different areas of the game and condensed them in useful presets.
Changing the bloom improves this game so much, it should be available to everyone!

Changes the bloom in the game, which is used aggressively in the shadow world, where it has a strong yellow cast. Can also remove the yellow tint by shifting the bloom color to blue. A too high value can cause a blue cast outside of the shadow world. Up to 50% is safe.

Here a comparison.
Native bloom:

50% bloom, 50% blue shift:

Bloom disabled:

I found more shaders connected to bloom, dove deep into glsl to understand them and improved this pack a lot!

• I apply the bloom level to the mask directly now, which results in a more even distribution of bloom when lowered. That also enables levels above 100% again.
• I found out how the color tint is applied (which is a static color that differs from area to area btw) and interpolate from that to an even luminance. Basically you can choose freely between intended tint and no tint at all safely without blue tint elsewhere now. (Let me know if you need custom color shift back, it didn't feel very helpful though)
• I found the shaders that color grade the shadow world darker and desaturate it. Not directly bound to bloom, but fits in this pack I think. For most that just find the shadow world too depressing, changing these settings is more useful than the bloom I think.

Here are some screenshots of the new version.
Native:

Recommended settings (I liked the most): bloom 50, tint 80, darken 20, desaturate 50:

And bloom disabled with the color grading removed also (compare to disabled above):

I also found some HUD elements missing in the RemoveHUD pack (textbox elements) and added those for screenshots.

The only thing I would like to add still is a setting for the periodic blur of the bloom, but I didn't manage to understand those shaders yet. I guess this could be solved better by ASM, to change the SIN/time var that controls it. If anyone knows that stuff, please help!
I found some get nauseated by the blur and I feel that's the only reason they disable bloom entirely. If you could change this, the bloom could be set higher.

I still think this game is better with bloom. It gives a lot of atmosphere to many places. But I agree that it is overdone a bit and more control over it feels nice.

I think both the description and some of the preset names could be a little more concise and cleaned up so that general users better understand the options and the effects of this graphic pack. Other then that, your screenshots seem like they'd help a lot of people!

So, I added simple presets and nested the finer options under a custom preset. That actually works very well.
By default you only see this and can select a preset:

But when you select custom, you can adjust the individual settings:

Same for color grading. I also reversed the logic and the name should now make very clear what they do:

Also added more to the description.
What do you think?

Here some saves to test shadow world. It takes an hour to reach it..
2. is first time shadow world (meeting midna), 3. is zanto gets midna cutscene

Oh, that looks great! Thanks for making the adjustments, looks good to merge. I do have two comments, but they don't have to be addressed.
