Hey everyone.

When writing new code with csharp-ts-mode, I've noticed there are a few cases where indentation is not automatically correct according to what is natural, nor what is convention.

For some cases, the indentation falls back to 0-indentation, and you have to manually add all the indentation back for things to look normal.

Examples:

- method call chains across several lines (indentation wrong on new-line)

- creating new objects (indentation wrong on first line after "new" - being unindented)

- array creation expressions (indentation wrong on second line, the one containing { - being overly indented )

Attached is a patch which fixes these behaviours.
