Release v0.16

[0.16] 2020-05-21

Added

• Async on_move impl for filer, files, grep and grep2 provider in Rust binary, no delay for the preview function. (#437)

Changed

• Decrease the max number of candidates for running in sync from 100000 to 30000, which means once the total number of candidates is larger than 30000, the async filter will be used, otherwise use the builtin sync one.
• filer uses the daemon job which requires the latest binary. Download the latest binary if you uses the prebuilt binary.

Improved

• Add cmdline completion for all the autoloaded providers. #429
• Run the spinner for dyn filter. #430
