Problem: There is no way to ensure a stable key order when encoding a JSON string, which can be useful for comparisons and producing cleaner diffs. Solution: Introduce a `sort_keys` option for `vim.json.encode()`,which is disabled by default. When enabled, object keys are sorted in alphabetical order. Adapts PR to upstream: openresty/lua-cjson#115.

I changed the memory strategy: encode_keybuf is now persistent between calls (like encode_buf with encode_keep_buffer). It's only allocated or freed when the settings change. What do you think, is this better? |

It is better, but we need to free it if it is too large. |

cjson.encode_sort_keys(enabled)option.If enabled, keys in encoded objects will be sorted in alphabetical order.
Uses the most performant approach to sort keys I could find. A small benchmark with comparisons is available here: https://github.com/skewb1k/lua-c-sort-keys-benchmark.
Fixes #66
