- remove the duplicated `max-height` rules for different parts of the power select dropdowns - they were interacting with each other and causing a large part of the lists to be unreachable
- bump the `bufferSize` so that enough dropdown items are rendered to fill the dropdown list
- filter the temporary tags that are created when using the PSM tags input so duplicates aren't visible in the tags dropdown filter

- updates width/height for non-square icons to match the desired dimensions (width+height have to be specified for IE11)
Changes introduced in #724 failed to take into account a few of our icons are not square (notably the `arrow-*-small.svg` icons) resulting in some icons appearing too small.
closesTryGhost/Ghost#8630
Add `width: calc(100% - 8px)` (substract 8px to keep a bit of a padding to the icon) to `.ember-power-select-search input` class so the input field is full width.

- fixes image uploads on settings/general by reverting to jQuery for triggering the file dialog because IE11 doesn't support `MouseEvent` events or have the `.closest` method on native DOM elements
- gives all SVG elements an explicit `width` and `height` - if one property is set to `auto` or not specified IE11 will treat it as 100% of the container
- fixes horizontal scroll + scrollbar on the main app viewport
