Fixed text reporting (missing constructor arguments)

[michaldudek]

Arguments for constructor of PHP_CodeCoverage_Report_Text were missing and they are required.

When running phpcov I got this:

$ php ./vendor/bin/phpcov merge --text true --html tests/coverage tests/coverage
phpcov 3.0.0 by Sebastian Bergmann.

and so on (many more errors).

This PR fixes it by passing the required constructor arguments based on few added CLI options - and their default values based on PHPUnit values.

The added options are:

• --low-upper-bound - default: 50
• --high-lower-bound - default: 90
• --show-uncovered-files
• --show-only-summary
• --show-colors

The last 3 only apply to --text report.

I also fixed an issue that Text report was not displaying - as the writer just returns a string to be output, doesn't write to stdout itself.

And finally I slightly changed behavior of --text option - it longer requires a value, but instead it is possible to configure whether it should use colored output or not via --show-colors option.
