v1.3 beta release 2

Fix for beta1: fix endless loop for nested lambda evaluation problems

This release opens a new dimension for generating deployment manifests by supporting access to status information of deployments. This can be used to influence the generation of multiple inter-dependent deployments described in a single yaml template.

Here is the list of new features:

• marshal and unmarshal yaml and json strings from/as parts of the yaml document (parse, asjson and asyaml)
• stream content from the yaml document into a command processing and catch its result (pipe)
• catch offers a possibility to handle evaluation errors
• sync supports the synchronization of the template processing with external content
• bcryptand bcrypt_checkcan be used to generate and validate bcrypt based password hashes
• write content to files
• keys function to determine a sorted list of map keys.
• option --path can be used to specify a sub path of the document for the output
• option --split can be used to split a list output into a multi document stream
• extend the reference lookup for nested merge function with access to outer bindings
• enrich the __ctx field to offer access to all levels of outer documents in merge functions.
• filtering of maps and lists via select[...] statement
• more maping flavors to procude maps instead of lists (map{...}and select{...})
• importing of multi documents (as list of nodes) with read mode importmulti
• access to defining scope in lambda functions using _
• scoped expressions with ( "alice"=25 ) expr
• improved error reporting with call stack of lambda function and location of parsing errors in dynaml
  expressions.
