Change name for 2 Themes and naming convention

[Mgldvd]

The reason why I changed the names of these two themes is because their main colors are the same, which are from 1 to 16. These are identical, while the background and foreground are what differs.

The idea behind standardizing the names is that if multiple themes have the same 16 colors, they should share the first part of the name, and only the lastname should change.

For example:

Mytheme
Mytheme Light
Mytheme Dark
Mytheme Galactic

In the example these four themes share identical colors from 1 to 16, but their background and foreground are different.

The cursor color does not create a new theme and would be considered a repeated theme.

• Homegrew -> Homegrew
• Terminal Basic -> Homegrew Light
• Ocean -> Homegrew Ocean
