2.5.0

• New step_from_min option makes every value min plus a whole number of steps: with min: 0.5, step: 1 the values are 0.5, 1.5, 2.5 instead of 0.5, 2, 3, and the grid labels follow the same scale. Off by default. An initial from/to, the handle limits and min_interval/max_interval should sit on that scale too; a value off it is moved to the nearest point
• New values_raw option keeps values entries exactly as given, so "20.0" stays "20.0" in from_value/to_value, in the input and on the label instead of becoming the number 20. Off by default. Spaces around the commas in data-values are ignored when it is on
• drag_interval: an interval whose width is not a multiple of step keeps that width while the bar is dragged, fires one onChange per step instead of two, and no longer ends up a step wider after a release. When the width is off the step grid the upper end now sits off the grid instead of the interval changing size
• The built js and css files on the master branch are now rebuilt and committed after every merge, so master always carries a current build between releases
• Issues: #505, #867, #869
