Bug: api.get_lightcurve should take in target name as well as targetid.

[emirkmo]

tendrils/tendrils/api/lightcurves.py

Line 27 in da578e1

params = {'target': target}

Fix:
Modify api.get_lightcurve to take in target name as well as target id by querying for target id if target is not castable to int.
