Updated Sublime Text plugin (Dkit)

[ryuukk_]

Hello,

LSP is nice, but is memory hungry.., consumes double than the 
actual completion engine (DCD)

I'm using Sublime Text and i found DKit [1], it's nice but is 
synchronous and was missing few bits that serve-d has, so i went 
ahead and i improved it in a fork (the project seems innactive)

I plan to continue work on this the whole week, so if you have 
suggestions, let me know

Config example:

```json
{
     // Path to the directory containing both dcd-client and 
dcd-server executables
     "dcd_path": "C:\\D\\dcd",
     // Port to use for DCD client and server
     "dcd_port": 9166,
     // Include path for existing source files.
     // DCD will also provide completion for dub dependencies
     "include_paths": [
         "projects/",
     ],
     "suppress_dependency_folders": false
}
```
