build,win: enable lint option to run "standalone"

This commit adds support to run the linter without running any other
targets. This commit also makes the lint task a little more quite and
more inline with the output on other operating systems.
Below is an example of running (with a lint error to show that it is not
so quite that errors are hidden):

C:\Users\danbev\working\node>vcbuild.bat lint
running lint-cpp 'src\*.c src\*.cc src\*.h test\addons\*.cc
test\addons\*.h test\cctest\*.cc test\cctest\*.h test\gc\binding.cc
tools\icu\*.cc tools\icu\*.h'
src\env.h:24:  Should have a space between // and comment
[whitespace/comments] [4]
Total errors found: 1
"C:\Python27\python.exe" tools/check-imports.py
running lint-js

The help message now looks like:
