Releasing 0.2 alpha2

New features

• Add permalink support: If permalink variable is defined, use it instead of file naming variable.

Misc

• Improved test coverage
• Add safety checks to make sure nothing is built outside of the build tree.
• Fix build with missing pages or posts folder in source tree

Changes since alpha1

• Major changes in the juliet new syntax:

In the alpha1 the juliet new command was taking two parameters: --date
and --title. This is absolutely not what we want because it restricts
the usage of juliet new to a very specific subset of article headers.

Instead we switch to a much more modular system:

1. juliet new

   Creates an article with default values.

   By default the article name formatting is $date-$title.md (title
   in slugified form). Default values for title and date are taken
   from the theme. It is highly recommended to the theme to let date
   being set by juliet (this can be done by _not_ specifying a default
   value for this variable). It is then set to the current date
   YYYY-MM-DD.

2. juliet new --file-name FILENAME

   Creates an article with default values in posts/FILENAME. For
   default, values, same as 1.

3. juliet new (-f FILENAME) -- key: value key2: value2 key3: value3

   Header values can always be passed as key value list after the --
   (stop argument processing). These values are then used for article
   name generation if filename is not specified + article header.
   Missing key values are defaulted using the theme default values.

   The syntax for the key-value list is as following: for each key/value
   pair:

   1. the key
      - optional: the key might end with a ':' character. This is just
         syntactic sugar, doesn't change anything.
      - keep in mind: the key can't contains spaces ' ', underscores '_'
         or colons ':'.
   2. followed by one or more space characters
   3. the value

   If the theme doesn't define default values, execution of juliet
   new is aborted with appropriate error message. That's why the
   theme should always specify proper default values if these are not
   going to be auto generated by juliet (like date_).

   In the future we will provide a hook-system which will allow themes
   to define Python hooks to generate values during juliet new
   execution.

The article name formatting (default: $date-$slug_title.md) can be
specified by the user using the filenaming_pattern config variable.
The pattern is in Python Template form (PEP 292). Accessible variables
are:

 - all command-line passed key: values
 - all theme side default values (overwritten by command-line passed
   key: values if key is identical)
 - all generated entries:
   o date_
     Either current date or, if specified by user/theme, the same
     value as the date variable
   o for each key, a slugified version of the key as slug_'key'. e.g.
     for title key, slug_title, date key, slug_date, etc.

EX:
    juliet new
    juliet new hello-world.md
    juliet new -- title: "Hello, world !"
    juliet new -- title "Hello, world !" date "1998-12-12"
