Motivation:
- Most test frameworks expect modules
- I'm told they're the future
Changes:
- Every typescript source file is now an es6 module
- Build system is now webpack (tho rollup makes nicer outputs)
- Outputs of buildsystem are one js file per entry point (background,
content, commandline_frame)
- These bundled js files are generated by traversing the dependency
graph of each entry point
In addition to scrollByLine and scrollByPage,
an excmd to scroll by half pages is included to
mimic default <C-u> and <C-d> behavior. In a
future revision, it may be preferred to have some
variable V for scroll values that pulls current
window height when called.
