Fawaz e0cca79526 Added : Photo EXIF Data in insert_photo() 
Added : Make Avatar from any photo
Added : Collection cover photo
Added : An array for thumb creations. Includes, code, width, height, watermark, sharpit
Added : Resizer class in common.php
Added : jquery.Jcrop.js in edit_account
Added : A common function called cb_filename. All filenames used in clipbucket follow a specific syntax
Added : Four new function for photos. get_original_photo, insert_photo_colors, insert_exif_data & add_custom_photo_size
Added : User Avatar collection functions. But they are not in use right now. This need proper thinking
Added : New files: mobile-form-class.php, resizer.class.php, exif.php, makers files for exif, jquery.Jcrop plugin, some template files
