v0.1.6

This is a small incremental release. Huge things coming in the next one though! :)

• Experimental mv-like="propertyName" attribute for copying templates from another collection. Property names are resolved in the same way as in expressions, except the current element is excluded (otherwise property="foo" mv-like="foo" would refer to itself). Collections created this way always start from 0 elements. Note that this allows infinitely nested collections where the children have the same template as the parent (e.g. comment nesting). In the future we plan to expand this beyond collections. Try it out and report bugs!
• Experimental mv-optional attribute (boolean attribute, no value) to create collections that start with 0 elements.
• When pasting an image, you will now be prompted for a filename. The auto-generated filename will still be there as a default.
• 50% speedup in expression evaluation.
• Raw GraphQL queries supported in Github backend (read-only, just like all raw API calls). To use, specify a URL like api.github.com/graphql#query{…}
• ordinal()/th() functions now only return the ordinal part (e.g. "th") without the number. This is to allow for more flexible formatting.
• Improvements in idify()
• Several other bugfixes and improvements.
