which control generation of HTML tags, CSS [ticket:39]

  all of MyghtyUtils merged into it now

  lines (#32)
- fixed single "#" comments in docs

  for specifying the error handler associated with encoding to
  'output_encoding' [ticket:40]
- the Template returned by html_error_template now defaults to
  output_encoding=sys.getdefaultencoding(),
  encoding_errors='htmlentityreplace' [ticket:37]

using a more portable **exception_kwargs collection
- added "source" member to the dict propigated to Lexer/Compile exceptions
- RichTraceback can access original template source as a unicode object
using either 'source' memebr on Lexer/Compile exception, or 'source'
property on ModuleInfo, fixes #37
- unit tests for #37

  allows much simpler and hopefully bug-free tracking of 'caller',
  fixes #28
- if plain Python defs are used with <%call>, a decorator
  @runtime.supports_callable exists to ensure that the "caller"
  stack is properly handled for the def.

  [ticket:34]

via <%page> or default_filters (but not those within the filter)
- added buffer_filters argument, defines filters applied to the return value
of buffered/cached/filtered %defs, after all filters defined with the %def
itself have been applied.  allows the creation of default expression filters
that let the output of return-valued %defs "opt out" of that filtering
via passing special attributes or objects.
- added support for "class" structures in ast parsing (i.e. class-level
data members wont get added to the "declared" list)

  expression-wise from the AST module  [ticket:26]

self.include_file(<filename>, **kwargs)

[ticket:24]

template (keyword arguments only, must be declared in that page's <%page> tag.)

propigates __nonzero__ method so it evaulates to False if not present,
True otherwise.  this way you can say % if caller:\n ${caller.body()}\n% endif

pre-process the ".." tokens before checking the filesystem

comments may contain quote characters [ticket:23]

  callable or list of callables which will be applied to the template text
  before lexing.  given the text as an argument, returns the new text.
- added mako.ext.preprocessors package, contains one preprocessor so far:
  'convert_comments', which will convert single # comments to the new ##
  format

- doc adjustments, changeset adjustments, modified unicode tests to
use ## instead of # for magic encoding comment.  # will still work for now.
- unsure whether we are going with #* *# or <%doc> for multiline comments,
looking like <%doc>.

  [ticket:16]
- cleanup in unit tests

- added "default_filters" argument to Template, TemplateLookup.  applies only to expressions,
gets prepended to "expression_filter" arg from <%page>.  defaults to ["unicode"], so that
all expressions get stringified into u'' by default (this is what Mako already does).
By setting to [], expressions are passed through raw.
- added "imports" argument to Template, TemplateLookup.  so you can predefine a list of
import statements at the top of the template.  can be used in conjunction with
default_filters.

magic encoding comment

file
- added modulename_callable to TemplateLookup to allow a function to determine module filenames
(takes filename, uri arguments).  used for [ticket:14]

with a template that indicates a non-standard encoding, are expanded into backslash-escaped
glyphs before being AST parsed [ticket:11]
