Merge branch 'master' into development

* Master contained dummy files for quickfix of empty temp folders problem.
03-a: Add fields for start time and end time.
03-b: Refactor Validations and add validation for time span.
03-c: Add basic style to uploader page.
03-a,b,c: Move validation errors to appear after submit button.
03-c: Add light shadow below uploader.
03-b: Bugfix - add parseInt for start and end inputs.

* Apparently these were being entered as strings, which throws off the comparison in the validation.
03-d: Pass start and end times to convert_to_gif.

* There doesn't appear to be a good way of testing the correlation between the start and end times passed in, and the length of the gif. FFMPEG::Movie.new() provides some methods for duration, length, etc. but these attributes return nil values on a gif file.
Ignore all but dummy files int temp_gif and temp_video.

* This way, any files processed in development will not be accidentally committed.
