fix an issue in js if there are more than 1 slideshow. The error was in options.before and was related to the settings variable. The issue was visible only if one of the slideshow had a carousel pager

add entity variable to field_slidehow_theme so that it can be accessed in template file (fix #1433282)

add back the pager and controls position option, fix #1502772. Also splitted the template and created a pager and a controls templates

themint active pager for image and carousel, also added a follow_activeSlide option for carousel [1482076]

[#1397156] fixed : due to a bug in image_style_transform_dimensions, added a manual calculation of images heights and widths
