timeRangeInputView: 100% width
videoLinkShell: bundle time controls in div
videoLinkShell: fix padding in start, end, & loops

padding was ugly in both timeInputs and cycleButton
videoLinkShell: fix spacing in loops button
less: remove `input { height: auto; }`

to height: 17.5px, while chrome and bootstrap both set it to 20px
shellEditorView: bugfix misaligned widgets
videoLinkShell: bugfix: full height videos in FF

videos played in firefox were occupying only a third of the available
height
