Bug fixes (Core Text), Services, etc.

This is mostly a bug fix release and many of the fixes are to the Core
Text renderer.  I think most of the really obvious display issues in
Core Text should be fixed now (one exception: dragging to resize a
window sometimes causese display tearing, but I can't decide whether
this is a problem that only occurs on my Mac).

The "Find Pasteboard" interaction has changed slightly to make it easier
to pull searches from MacVim into other apps.  Previously, if you hit *
on top of some word, e.g. "test", and then hit Cmd+g in another app,
then that app would search for "\<test\>" and consequently fail to find
anything.  I have fixed this and some other common problems (related to
using the "Find Dialog").

I also want to mention that I have rearranged the Services menu so that
it works better on Snow Leopard (hopefully I did not break anything on
Leopard and Tiger).  There are now two entries: "New MacVim Buffer With
Selection" which opens a new buffer with whatever text is selected, and
"New MacVim Buffer Here" which opens a new buffer and sets the pwd to
that of the file or folder you had selected (in Finder).  Note that on
Snow Leopard you can access the Services menus by right-clicking, which
makes them a whole lot easier to use than on Leopard and Tiger (e.g. try
right-clicking a file in Finder, or select some text in Safari and
right-click the selection).  (The "Open Selected File" Service has been
deprecated since it was not very useful and it was kind of confusing as
to what it really did.)

A warning: it is possible that this release will break Ruby plugins due
to a patch to mainline Vim (which changed return types of certain
functions from String to Fixnum).  For example, the LustyExplorer plugin
broke because of this (but has subsequently been patched).  At any rate,
if you have any problems with Ruby plugins after updating to snapshot 52
you should contact the plugin maintainer.

  - Ctrl+Tab works (Core Text)
  - Improve Cmd+g behavior in other apps when repeating a search that
    originated in MacVim
