RangeTool overrides xlim setting

[andreasf-ki]

Hi there.

Observation:
When using "xlim" together with "rangetool = True", the "xlim" values are ignored and the rangetool overrides w 75%-100% default x-range.

Issue:
Depending on the use case and / or the data shape on y-axis (especially in the absence of y-axis autoscale #101), this leads to unintuitive bahaviour and awkward looking initial plots.

Proposal:
Carry the xlim values forward to "__initialize_rangetool(..., xlim)" in plot.py and use this to determine initial range in
start_index = int(0.75 * len(source["__x__values"]))
p.x_range = Range1d(source["__x__values"][start_index], source["__x__values"][-1]) .

Any thoughts highly appreciated.
