Writing a newline should indent the text that follows

[dsherret]

It will slow it down a bit, but doing writer.write("my string\ntest") should:

1. Change \n or \r\n to the newline character specified when creating the writer
2. Add the correct amount of indentation after the newline.

Essentially, it should just take the inputted string and do:

(str || "").split(/\r?\n/).forEach(s => this.writeLine(s));

Add in future maybe: a function called writeWithoutAutoIndent(str: string) for people to use to bypass this functionality?
