Change Log

- C++
- 7b5dad16dd3d96e44a9291d9323bdfa65990da3f Added mode-specific properties. For example, only when running in `OpenCL` mode the kernel compilation will be verbose:
c++
{
kernel: { verbose: false },
mode: {
OpenCL: {
kernel: { verbose: true },
}
}
}

- 57746d5b5398e3f05efe4868444e593c8ad085f7 Added unicode parsing to `occa::json` (still keeps it as `\uXXXX` for the user to parse)

Bug Fixes
- C++
- 98 Setting `OCCA_VERBOSE` works
- C
- 2db622c480e439b4f60c9491260a1248261b0777 `occaPtr` fix

Change Log

- C++
- 5249d4c0a69ce4eec6b52f2ab60d8eb1206ee002 Added occa::getKernelProperties() to setup default kernel properties (e.g. `props["headers"]` as an `array` type)

- C

The biggest change is the introduction of `occa::properties`.
We use `occa::properties` as a way to generalize the OCCA API to support current backends as well as future ones.

It supports [JSON format](http://www.json.org/) with some Javascript short-hand notations:

For example:

JSON:
{
"1": [1],
"2": 2,
"3": "3"
}
Shorthand:
{
1: [1,],
2: 2,
3: '3',
}


The differences:

* Supports trailing commas
* Doesn't require quotes for object keys
* Can use single quotes for strings

Since the `occa::properties` is a key-value store, it doesn't require the enclosing `{}`
