Additions and changes

Drop internal implementation of OrderedDict and use the standard library collections.OrderedDict instead
Implement Dockerfile for running asciidoc
Add Catalan translation
Add docbook5 backend
Fix misspellings in various files and documents
Use UTC for testing instead of Pacific/Auckland (which observes daylight saving time)

vim-asciidoc: speed up the refresh process for big files (thanks @aerostitch)
Allow specifying floatstyle attribute for figures, tables, equations, examples in docbook (thanks @psaris)
Use trans python module (if available) to better handle character decomposition to ascii for ascii-ids (thanks @rkel)
