rbutil: Merge rbutil with utils folder.

rbutil uses several components from the utils folder, and can be
considered part of utils too. Having it in a separate folder is an
arbitrary split that doesn't help anymore these days, so merge them.

This also allows other utils to easily use libtools.make without the
need to navigate to a different folder.

+This is Rockbox Utility, the graphical installer and housekeeping utility
+for Rockbox.
+
+Requirements:
+=============
+- gcc
+- Qt 4.5.0 or later
+- at least the following folders from Rockbox svn:
+  o lib/rbcodec/codecs/libspeex
+  o rbutil/
+  o tools/
+- libusb (Linux only)
+
+Building:
+=========
+- run qmake
+- run make
+
+Build Options:
+==============
+- static
+  add "-config static" to the qmake call to build a static binary. Note that
+  this also requires that you have a statically built version of Qt.
+- dbg
+  add "-config dbg" to build with debug symbols.
+- silent
+  add "-config silent" to the qmake call. This is an undocumented feature of
+  Qt itself. Note that this doesn't seem to work on Windows and Mac OS X until
+  recent versions of Qt.
+
+Installation / Deployment:
+==========================
+Rockbox Utility is build as all-in-one binary. This means for distribution
+you need:
+- RockboxUtility (main binary)
+- rbutil_*.qm (translation files, only for non-static builds)
+You don't need any other files like configuration files, especially
+rbutil.ini which will get included into the binary.
+
+The script utils/common/deploy-rbutil.py automates building deployment
+binaries. For a complete list of paths to get from svn to build please check
+its source.
