Improved formatter

[JCWasmx86]

This improves the formatter:

1. Break long lines (At the moment 120, but this should be configurable somehow, maybe use the average or something like that)
2. Indent broken up parameter lists
3. Fix _("Foo") and so on
4. Fix the bug that new Gee.HashMap<string, List<string>> () is reformatted as new Gee.HashMap<string, List<string> > ()
5. If formatting fails, print commandline to stderr in order to debug e.g. uncrustify failures

Is this mergeable (After squashing the commits)?

@Prince781: Do you have any time to rereview these changes?

[Prince781]

uncrustify will fix a space before the call to x() and remove the space before the translation function, but it will not do anything to the hashmap calls.

void x () {
}

void main () {
    new Gee.HashMap<string, Gee.List<string>> ();
    new Gee.HashMap<string, Gee.List<string>> ();
    new Gee.HashMap<string, Gee.List<string>> ();
    new Gee.HashMap<string, Gee.List<string>> ();
    new Gee.HashMap<string, Gee.List<string>>();
    x();
    _ ("Foo");
}

Should be fixed now, failed CI for Vala Daily seems to be unrelated

I haven't forgotten about this. I promise I'll get to it after I get through my latest crunch.

@JCWasmx86 thank you very much
