Rewrite the input buffer.

[Windblade-GR01]

Currently the input buffer present some problems that make it harder to execute commands.
This is show on these cases like #116.
And any improvements like ones done by NeatUnsou break the functionality of current one.

So to solve problems and allow improvements in the future a full command buffer rewrite is needed.
As compatibly with MUGEN is pority this new buffer would be fully backwards compatible with MUGEN chars.

I closed the issue about keeping 0.94-0.97 input parser as an optional. Once Gacel releases his own input parser it would be good to have an option on the config.json to choose between the two, while Gacel one will be the one turned on by default.

I have a similar problem as in #116 with my chars
Except it's the opposite problem. When I press forward or backwards, I always get the same result as if I had pressed FF (double forwards) or BB (double backwards). It's really annoying me, I can't just simply walk, I'm always dashing!

EDIT
I must mention I just tried again on WIndows and found out this only happens to me on Linux! Inconsistent behavior huh?
