v0.2 - Theme Maker

this release aims to simplify creating Nimib themes such as nimibook.

It does this through the following changes:

• instead of creating and injecting multiple variables
  (nbDoc, nbBlock, nbHomeDir, ...), nimib now only injects a nb variable
  that is a NbDoc. Some aliases are provided to minimize breakage.
• handling of paths (srcDir and homeDir) is changed and is based on the presence
  of a new config file nimib.toml
• command line options are now processed and can be used to skip/override the config process.
  Run any nimib file with option --nbHelp to see available options.
• note in particular new --nbShow option which will automatically open the file in your default browser.
• nbPostInit and nbPreSave customization mechanism based on includes are now removed
• documentation has been updated to reflect the above changes and also to add other Nimib references (NimConf video, nimibook, getting-started, ...)
