Trim down snippets and add new

The point of this was to add some new snippets that I need, and get rid
of the ones that I don't want. The point of this is that I don't want to
wade through snippets which aren't actively used when I go to look at my
snippets.
Change path of phputils and consolidate (make room for utils for other languages)
Load commands.vim early to allow setup project environments in .vimrc
Change the way php.vim helps manage dependencies

Previously, <leader>use over a class name would locate the class, and
put a use statement at the top of the file. Now, <leaer>use anywhere in
the file will update all of the dependencies for the file (including
removal). This is a little dangerous since the evaluation of
dependencies is just done with a heuristic, but I don't anticipate
frequent failure and it's more a matter of good code hygene than code
critical decision making.
php.vim hygiene

Made some functions local, removed php filter function (not really
necessary and I would rather create bindings or add the scripts to my
path than have a function which essentially appends the path to the
scripts directory).
Prevent double loading of commands.vim
Fix completion type for Proj command
Fixup commands.vim indentation
Move project environments out of commands.vim
Prevent double loading of pluginOptions.vim
Disable code folding
Removed Fugitive

I don't like the workflow introduced by fugitive because, while being
slightly more convenient, it's not as expressive as git on the command
line. I don't like contortions that happen to my brain when I try to
figure out which fugitive commands correspond to which git commands.
Add mapping to open url under cursor in firefox
Add/revise php snippets
Fix, call PhpDoc should not be local
Fix, command Bufdo->BufDo
