Revert some Steve Losh-inspired search settings
Revert some Steve Losh-inspired search settings

It turns out I didn't really care for these particular settings - I
start off searches far too often and then erase the string for this to
work out - it just winds up costing me keystrokes. Also, the
Vim-specific regex is somewhat better suited to searching code than I
gave it credit for - "$" not being a default special character is of
particular use, and now that I've gotten used to it, having to remember
to escape it every time I want to search for a Bash/Perl variable is
tedious.

Also, global replacement is another thing I've just gotten used to, and
much like disabling <Esc> was ultimately a bad idea cause it broke with
standard configuration on most default installations of Vim, changing it
here means I won't remember what's happening elsewhere, or vice-versa.
It's just more confusing than it's worth for me.
