ZODB Components: ModuleSecurityInfo() should also apply to the alias module, not only to the versioned one.

This fixes an Unauthorized error when GitLoginError is imported from
erp5.component.module.Git defining ModuleSecurityInfo() for __name__
(erp5.component.module.erp5_version.Git).

Note that when migrating the content of a Product, ModuleSecurityInfo() first
parameter must be __name__.

ZODB Components: Alias module was not added to sys.modules if the module it points to had already been loaded before.

- revert parallel gadget loading
- minor refactoring on appcache storage creation

- new skin folder with project quick view form, scripts and gadgets
- front page redirects to custom project module

with namedtuples and unicode literals enabled, our patch break with:

    Module py2stdlib, line 266, in infer_named_tuple
      ''' % {'name': name, 'fields': attributes})
    Module Products.ERP5Type.patches.pylint, line 74, in string_build
      encoding = _guess_encoding(data)
    Module astroid.builder, line 65, in _guess_encoding
      if string.startswith('\xef\xbb\xbf'):
    UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128)

because pylint/astroid uses string_build to evaluate the named tuple and the source code enabled 
unicode_literals future, string_build is called with an unicode object.

To avoid duplicating _processSearchValue.

Scriptable keys are already handled by other branches below.
If one wants to provide a string or dict value to a scriptable key, they
need to wrap it into another type to disable catalog processing of these
values.

Also, add a missing ignore_unknown_columns parameter.

These are only accessed within methods which are not reachable from
this SearckKey type, so this was essentially dead code.

This allow using measure.updateCellRange to create varianted measures
programmatically.

Remove the TALES for lines, columns and tab on the matrix box because
the default behavior is to call this updateCellRange script

As was initially intended, but visible a directory level got lost in an
intermediate patch file.

* This didn't work anyway with concurrent processes using the same SVN working
  copy (which is a frequent use case nowadays).
* Now that it has been migrated to ZODB Components, this also breaks on reset:
  1) Thread T1 acquires the lock.
  2) Thread T2 performs a reset.
  3) Thread T2 loads Subversion and thus a new RLock instance is created.
  => T2 can acquire the lock.

Moved 'git_askpass' shell script to product/ERP5/bin (considering that this
is a very short shell script which hasn't changed in 7 years, no need to move
it to the ZODB which would require creating a temporary file...).

After updating erp5_forge, you should delete 'product/ERP5VCS/' directory
as this will only contain '.pyc' files.

This fixes the issue that a truncated traceback followed the json.

This is a backport from Zope (see commit
9c8dd7672cbef67573b3641178f12337c80de074).

>>> True and [(1,2)]
[(1, 2)]
>>> False and [(1,2)]
False
>>> [] and [(1,2)]
[]

This is needed for compatibility with existing actions.

Fields must propagate all values requested by ERP5.

Add a new url_generator mode

Do not redirect to 'view': let the js handle the default navigation

Do not generate view url if document does not acquire the hal web section
