Accept wildcards in the parser screen

All compatible Keys are passed on to the parser, for parsing in a combined
hex-key.  "Compatible" means all keys have the same number of columns and
the same style separators, and only 1 (optional) has a header.  Incompatible
sets complain in the parser GUI.

Merge branch 'master' of github.com:0xdata/h2o
I Hate Git, all my files are not pushed
michal made me do it. add the build_cloud_with_hosts option to the rest of the testdir_single_jvm tests
so they can all be run with -cj <config json> option to dispatch to other machines (they will run however the config says, so can be multi jvm). I put the same args from build_cloud to build_cloud_with_hosts, to override the default config, just to be sure it's the same build_cloud as it would do for localhost (like on your laptop)
a couple tests I hadn't pushed also.
a couple of missing things around import h2o* in the last push

and now added back by me)
