dynamic dialog size for DialogSelect.xml
Fix marking a video with a resume point as watched.

Although the video was being marked as watched, the resume point wasn't cleared.
CFileItem::GetPath() returns the virtual library path, causing
CVideoDatabase::GetFileId() to return -1 as it couldn't find any actual file and
CVideoDatabase::ClearBookMarksOfFile(int) was never called.

This commit also fixes an incorrect use of SetPlayCount(1) when marking as
watched by replacing it with IncrementPlayCount().
[ios] - add the launchimage for iphone5 screens to the info.plist - restores iphone5 resolution on ios8
[ios] - replace the launch images holding the XBMC logo with plain black images (as those aren't shown on most devices anyways and our startup time is fast enough to not need visible launch images)
