Merge pull request #5 from yeputons/issue-4

#4: fixed 'npm test' start on Windows by removing paths to 'pogo' and 'mocha' - npm adds them to PATH automatically
spawn_test.pogo: extracted 'spawn and wait for' function
Added 'spawns a batch file' test
added 'passes arguments with spaces to batch file' test
spawn_test.pogo: replaced \\ with \ (no escaping in Pogo?)
More tests with batch files and spaces were added
test spaces args.cmd: fixed mistypo
Added 'escape quotes and slashes properly' test with argv.c
#3: first attempt of fixing, this iteration passes all tests on Windows, looks like fixed
package.json: added 'argv.c' compilation to the 'test' script
.gitignore: added test/argv.exe; test/argv
Escape empty string properly
