Capture named screenshot

[phatmann]

When capturing screenshots manually you may not want the line number and source file in the screenshot name. This commit adds this functionality. It places the screenshots in subfolders based on device and system version used and appends device orientation to name, so runs on different device, OSes and orientations don't clobber each others screenshots.

A problem I'm having is that from name, I can't tell the functional difference between captureScreenshotWithDescription: and captureScreenshotNamed:.

Inside, the first is:

{filename}, line {line}, {description}

The second is:

{name} ({orientation}) {idiom}-{version}

A lot of the information from the second I would want to include in the first. I would rather see captureScreenshotWithDescription: enriched, producing:

{idiom}-iOS{version}/{filename}, line {line}, {description} ({orientation})

I would be happy to "enrich" captureScreenshotWithDescription as you suggest now that I know you approve of this approach. I will add this change to the pull request asap.

I am going to close this pull request, because there are better ways of doing screenshot compares. See LELA or ios-snapshot-test-case.
