Big progress in the v1 of karoake ruleset.

Because seems it's not easy to implement all the features in this release, so will just focus on the current parts

Editor:

• Fix all the issues in the import lyric step.
• Finish the check manager.
• Finish the current lyric editor (Except edit note feature, will not be able to let the user touch it in the V1 release.)
• Fix all the features in the singer and translate editor.
• Able to save/load JSON beatmap with no data lost(Should be able to save the data like singer list or translate list).
• Deal with undo/redo issue.

Config:

• Fix the style adjustment in the config(or might not have the config in the first release?)

Skin:

• Write a customized shader for v1. The user can only adjust the parameters in the current shader(because too much shader might cause a performance issue).

Gameplay

• Fix wrong style with playback issue.
• Might remove Container<DefaultLyricPiece> in the DrawableLyric because we can separate the lyric by shader eventually.

Not really sure will be implemented in the V1:

• Ruleset Translation.

Those parts are still planning(will be moved into V2 or later):

• Customized shader and save in the skin.
• Customized font in the skin(with .fnt format).
• Layout and style editor.
• Lyric animation.
• Scoring system.
• Implement classic stage editor to deal with start and end lyric time.

For the V1(current version). the main goal is:

• Let users be able to edit the karaoke beatmap from zero.
• Able to see the fucking lyric.
• Able to switch the stage by mod.
• Able to customize base style(e.g: color, font style, sizing, and outline). -> This feature will be moved to V2 because need more time to think how to let user edit the shader and able to adjust the params in the stage.
