[FeatureRequest] - Horizontal layout improvements

[mmbossoni]

Describe the bug
1- Horizontal layout text is not vertically aligned or could be more packed when using no_margin and compact
2 - Allow for separator color to be specified (and not inherit from VRAM)
3 - Text outline is black for separator and doesn't honor transparency (at least it doesn't seem so)
4 - Throttlestatus doesn't play well with horizontal (it shows an empty space with just the separators)

List relevant hardware/software information

• Linux Distribution: ArchLinux
• MangoHud version: Git
• GPU: GTX 1070

To Reproduce
Steps to reproduce the behavior:
1- Use attached MangoHud.conf file and change text outline from 0 to 1 and see bug 1
2- From attached config, change text outline for 0 to 1 and see bug 3

Expected behavior
1 - text properly aligned (related to separators) or smaller separators or baseline align with frame graph? maybe a "text align" property (top, center, bottom)?
2 - A new config option to specify separator color (or being able to remove it altogether)
3 - Separators have the same outline color as text
4 - For fields like throttling status maybe it should hide everything (text + separator) if not throttling?

Screenshots
throttling creating empty space + text not vertically aligned with separators

text outline=1 (notice separator outline is darker than text outline)
