Description

Capability to load built-in vscode plugins to Theia
Looking at grunt, gulp and jake

Reproduction Steps

Put the jake, grunt and gulp vscode built-in plugins into the theia/plugins folder
unzip/untar the test project attached
npm install // to build the node_modules
Start theia and load the test project into the browser
Note:
1- Load the test program (Note, just to test that we can extract the task as "GULP, GRUNT, JAKE, NPM"
2- For Jake, still under investigation

OS and Theia version:
Ubuntu 16.04
Theia 0.5.0

Diagnostics:

test.tar.gz

Jake is using the old API to computeTask(). Because of that, I need to implement the deprecated Task constructor to handle Jake.
To support the vscode built-in plugin for JAKE , there is two ways:
1- I need to implement the deprecated Task constructor to handle Jake.
2- Jake vscode built-in plugin needs to be adjusted to handle the creation of task using the newest API

In the current solution, I implemented solution 1, so we can support JAKE until vscode modify the Jake plugin

For solution 2, we need to modify:
File: jake/src/main.ts
Method computeTasks() at ~line 145, need to modify the following line by adding the workspaceFolder as a parameter:

OLD:
let task = new vscode.Task(kind, taskName, 'jake', new vscode.ShellExecution(${jakeCommand} ${taskName}, options));

NEW:
let task = new vscode.Task(kind, this._workspaceFolder, taskName, 'jake', new vscode.ShellExecution(${jakeCommand} ${taskName}, options));

For testing purpose, you need to add in the package.json the following packages. (Either in devDependencies or dependencies)
"dependencies": {
"gulp": "latest",
"gulp-util": "latest",
"gulp-sass": "latest",
"gulp-coffee": "latest",
"gulp-uglify": "latest",
"gulp-concat": "latest",
"gulp-connect": "latest",
"grunt": "~0.4.5",
"grunt-cli": "^1.3.2",
"grunt-contrib-jshint": "~0.6.4",
"grunt-contrib-nodeunit": "~0.2.0",
"grunt-contrib-watch": "~0.5.3",
"jake": "^8.1.1"
}
With those packages installed, you can test "Gulp", Grunt", "Jake" and "npm" if installed

If this API is still into https://github.com/Microsoft/vscode/blob/master/src/vs/vscode.d.ts then we have to support it regardless whether it is deprecated or not. Just mark them as deprecated as well.

it is still there so yes (BTW PR is doing that)

This is what I did, I put deprecated with the constructor (Same as in vscode)
