Merge arrays and read multiple documents

Resolves:

• Ability to read multiple documents in a single file: #157
• Feature Request: Append list items instead of overwriting: #128

Fixes writing in-place with docker

Fix for #156.

Minor fix to help text, -j --tojson no longer appear as global options as the only work for the 'read' command.

Multiple Document Support!

Finally added multiple document support!

Use the '-d' argument to specify a particular document, default to 0 (first doc) if not specified.

yq r -d1 content.yaml this.deep[0].path
yq w -d1 content.yaml this.deep[0].path newValue
yq w -d'*' content.yaml this.deep[0].path newValue

Backward breaking change
A result of this is that now only the read command supports the JSON output flag, all other commands do not (as you cannot have multiple documents in a JSON file. If you still want JSON output you'll need to pipe:

yq w -d1 content.yaml this.deep[0].path newValue | yq r -d1 -

Fixed #9

Currently in beta and available just in Git - will promote to brew, snap etc shortly

Fixed #9

1.15.0

Implemented a delete command and associated tests for deleting a node from YAML input. This behaves in a similar manner as the write command.

The following functionality is not provided, although could conceivably be added with a modicum of additional effort if there is strong opinion that they are required:

Specify the node(s) to delete using a script (as with the write command)
Deleting common elements from all members of an array (deletions from individual members are supported using a path like a.b[0].name, but deleting from all instances in one pass, e.g. a.b[*].name, is not).

Thanks @mhuxtable !

Print multiline strings plainly

Multiline value fix - multi line strings no longer printed as a yaml block

Although printing the string as a yaml block can be argued to be technically correct, in practical terms it's more useful to just print out the multiline string as is.

Fixes #121 and #104
