returns the time.time() when the module

workarounds; its AST matches CPython's pretty closely

  <%page> args named the same as a __builtin__ would not
  honor the default value specified in <%page> [ticket:93]

better support grouping

  to be used in place of sys.exc_info()[2].  html_error_template()
  and text_error_template() accept an optional
  render()-time argument "traceback" which is passed to the
  RichTraceback object.
- lexer tests now rely upon an always-sorted dict repr()

  http://techspot.zzzeek.org/?p=28 has now
  been added as a built in syntax, and is recommended
  as a more modern syntax versus <%call expr="expression">.
  The %call tag itself will always remain,
  with <%namespacename:defname> presenting a more HTML-like
  alternative to calling defs, both plain and
  nested.  Many examples of the new syntax are in the
  "Calling a def with embedded content" section
  of the docs.

- added "cache_enabled=True" flag to Template,
  TemplateLookup.  Setting this to False causes cache
  operations to "pass through" and execute every time;
  this flag should be integrated in Pylons with its own
  cache_enabled configuration setting.

use Beaker 1.0.4, just checked in.   This version of Beaker stores
no persistent state in memory for each key, allowing dynamically
generated keys to work without using up available memory.

cache sends in a "defname" parameter so that the cache can map settings to that name, instead of the key.
eliminates the need to store all Value objects which will use up RAM in a dynamic-key scenario.

  e.g.  ${local.cache.get('somekey')} or
  template.cache.invalidate_body()

- the Cache object now supports invalidate_def(name),
  invalidate_body(), invalidate_closure(name),
  invalidate(key), which will remove the given key
  from the cache, if it exists.  The cache arguments
  (i.e. storage type) are derived from whatever has
  been already persisted for that template.

and babel is responisble for stripping them when necessary
o remove the no longer needed Unicode/Str ast hack for Jython

adds support for Jython 2.5

fixes #90

- removed unnecessary attributes from DefTemplate.
- added ModuleTemplate class, which allows the construction
of a Template given a Python module generated by a previous
Template.   This allows Python modules alone to be used
as templates with no compilation step.   Source code
and template source are optional but allow error reporting
to work correctly.

container classes, so cache types such as
"ext:google", "ext:sqla", etc. are available.
memcached is available as both "ext:memcached" and
"memcached", the latter for backwards compatibility.

a magic encoding comment

an expired section, instead of the original context
passed in [ticket:87]

a cached block would raise an error when called within a
cache-refresh operation that was initiated after the
initiating template had completed rendering.

this version (fixes incompatible compile symbols from 0.1
series).
- added a few docs for cache options, specifically those that
help with memcached.
