Allow substitution of messages as variables in other messages.

This is part of a manual merge of changes released to the internal branch 2008/06/11.  Original author is Marc-Antoine Parent.

In addition to the merge, bring in all language directive mappings and codepage mappings from the latest internal version of grit to avoid warnings related to unknown output languages.  While updating the mapping, fix the name of the fake-bidi language.  Finally, to help debug differences in data_pack files, add a simple ASCII converter to data_pack.py

This is a bit of a preview as in its current state the change modifies the
output of generated_resources_fake-bidi.pak in a way I don't yet understand, and
causes some warnings to be printed out during compilation, e.g.

Warning:GetCharsetIdDecimal() found undefined language
Warning:GetLangCharsetPair() found undefined language
Warning:GetLangIdHex() found undefined language
Warning:GetCharsetIdDecimal() found undefined language
Warning:GetLangCharsetPair() found undefined language
Warning:GetLangIdHex() found undefined language
Warning:GetCharsetIdDecimal() found undefined language
Warning:GetLangCharsetPair() found undefined language am
Warning:GetLangIdHex() found undefined language am
Warning:GetCharsetIdDecimal() found undefined language am
Warning:GetLangCharsetPair() found undefined language bn
Warning:GetLangIdHex() found undefined language bn
Warning:GetCharsetIdDecimal() found undefined language bn
Warning:GetLangCharsetPair() found undefined language es-419
Warning:GetLangIdHex() found undefined language es-419
Warning:GetCharsetIdDecimal() found undefined language es-419
Warning:GetLangCharsetPair() found undefined language fa
Warning:GetLangIdHex() found undefined language fa
Warning:GetCharsetIdDecimal() found undefined language fa
Warning:GetLangCharsetPair() found undefined language fake-bidi
Warning:GetLangIdHex() found undefined language fake-bidi
Warning:GetCharsetIdDecimal() found undefined language fake-bidi

Tony, this is ready for review now.

There is still a minor difference in the grit output from the Chromium build
compared to the previous version of grit, but I think it's a beneficial change
and the previous version was a bug:

Sorry, that was missing some context.  The diff is a diff of the output of
[tools/grit/grit/format/data_pack.py $PACKFILE] for PACKFILE set to the before
and after filename of the generated_resources_fake-bidi.pak file that is the
only file showing a difference.

Cheers,
Jói
