Initial commit

This will enhance php-mode for Emacs with support for new keywords
which wre added as part of 5.4, such as traits.  This makes formatting
more readable since fewer things are treated as barewords.
Add a README file for Github
Make the underscore a symbol constituent

This makes it possible to use commands like M-f and M-b to move back
and forth through words in variable names suck as $foo_bar_baz, while
currently php-mode treats the variable as a single name.

The idea for this change came from an email by Deniz Dogan on the
Emacs development mailing list.
Update the README with credits and feature information
Add license information to the README
Show traits in Imenu
Add support for namespaces
Treat ‘.php5’ as a valid file identifier

I have rarely come across this before, but nonetheless have
encountered it out in the wild.
Delete all commented-out code

I do not see any reason to keep that noise around.
Fix the regex for namespaces via Imenu
Allow backslashes in namespaces for Imenu
Change the commentary to not mention PHP 3 and 4 explicitly

The mode tries to support anything later than PHP 3, so there is no
reason to give off the mistaken idea that we do not, for instance,
support features from PHP 5.
Remove the comment about the Changelog which does not exist
Fix font-locking for namespaces, classes, and traits

The are incorrectly given the warning face due to an incorrect
character class used in the regular expression for matching against
their names.  We will fix this part of the expression, while also
allowing backslashes to support namespaces, so that namespaces,
classes, and traits will be given the proper face.
