Quiet by default

[mbrodala]

Right now the linter is rather verbose by default, for example if checking an empty file the following output is shown:

Linting input file test.ts.
=> Executing sniff Helmich\TypoScriptLint\Linter\Sniff\IndentationSniff.
=> Executing sniff Helmich\TypoScriptLint\Linter\Sniff\DeadCodeSniff.
=> Executing sniff Helmich\TypoScriptLint\Linter\Sniff\OperatorWhitespaceSniff.
=> Executing sniff Helmich\TypoScriptLint\Linter\Sniff\DuplicateAssignmentSniff.
=> Executing sniff Helmich\TypoScriptLint\Linter\Sniff\NestingConsistencySniff.

CHECKSTYLE REPORT

SUMMARY
0 warnings in total.

This makes it rather hard to notice real warnings and messages when checking dozens of files, thus I'd suggest not outputting anything by default unless -v is passed.

A dot progress similar to phpunit could be used instead to indicate activity but this requires support for recursive directory traversal which in turn requires a --pattern option or similar (#19) to cover the myriads of possible file extensions.

Changing the default output format would be a breaking change. I'll probably add a new (non-default) output formatter first, and then maybe change the default output format in an eventual 2.0 release.

Personally I don't see a breakage here, unless someone went through the hassle parsing the lint output. What issue do you see here?

Thanks for your input. I've reconsidered my position on this and agree with you. #29 changes the default output to something less verbose. The old behaviour will still be usable, but has to be explicitly enabled via a command-line flag.
