Sort on empty option

Option to control sorting the list when there is no input

see g:fruzzy#sortonempty
Default value is 1 which means that when denite is brought up for file paths, the list will be sorted based on how close each entry is to the current buffer.
To turn this off, set to 0.

Other changes

Current version is no longer output to the messages window when Denite is brought up. To check version of plugin, :call fruzzy#version after activating it through denite. See readme for full details.

Report mod version

No functional changes. Just added a method to report git sha from the native module to aid debugging.

CPSM like similar file bounce

When input query is empty, sort candidates based on levenshtein distance from the current file; Also do not show current file.
This makes bouncing between similar files (.h/.cpp) or (xxx.py/xxx_test.py) really convenient.

PS: I build windows and linux binaries. Mac binary is donated by a contributor.
If you'd rather not run these binaries, then just build it from source - it's easy.

First release

Getting started :)
