Plugins + Scripts Timeline

- Fix crash to desktop when importing mocap
- Split mocap to a separate screen
- Improve mocap import performance

- Improved mocap import (closer to the original animation but longer to generate, snap to specific times, also check rotation)
- Keyframe reduction for float params (e.g. for LFE's face mocap)
- Greatly reduce the amount of time to process modifications on large animations (by an exponential factor)
- Make the reduce technique configurable
- Fix dope sheet not resizing after animation length change

- Remove previous animation on merge load instead of merge

- Do not stop the animation when disabling the plugin
- Fix #31: Import mocap will report errors when importing

This is a major release of Timeline, with a breath of new features and a brand new user interface! And bug fixes! And I'll write actual release notes later. Check it out!

- Move import export to the left
- Configurable and faster interpolation
- Prevent importing while importing
- Remove "timline" from import/export buttons

- Revert import/export animations to .json
- Import and export now include the original controllers positions (excluding root)
