fix(provider): read TS Lint indent size

[mattyclarkson]

The TS Lint indent rule can specify the indentation size:

"indent": [true, "spaces"]

"indent": [true, "spaces", 4]

"indent": [true, "tabs", 2]

This patch allows tsfmt to read that size and correctly set the formatting options. This means that tslint and tsfmt do not fight over the indentation size.

@vvakame not sure if the travis error is a result of this patch?

[mattyclarkson]

@vvakame any chance you could have a look at this? Would be a really good quality of life improvement for the project; means that with a tslint.json there is zero need for a tsfmt.json if there is a change in indent specified.

I'm not sure why console is being defined globally twice on the CI.
