v0.1.10

• minor tweakings in the completion and inspection APIs (#234)
• illustrate completion and inspection from the echo kernel (#234)
• when installing kernels globally, install those under /usr/local rather than /usr (#236)
• allow interpreters to handle completion requests asynchronously (#242)
• try to process completion requests straightaway instead of queuing them along execute requests and all (#242)
• add back optimized JSON printer from former jupyter-scala versions, so that large response payloads don't unnecessarily slow down the kernel (#243)
• allow to send kernel console / logging output to a separate file, to ease debugging (pass --log-to /path/to/log.txt to enable it, #243)
• tweak almond-spark progress bar style (for better rendering in nteract, #244)
