MainBuildRules: recent gcc4 no longer supports -nostart.
BuildSettings: Explicitly specify DWARF 4 in debug mode.
Merge branch 'lastgood' into bnetapi
Jamfile: Remove Install rule invocations

Automatically installing stuff in /boot/home/config isn't desirable.
generate-build-info.sh: make optionally work outside git repo

If the build variables WEBKIT_REVISION and HAIKU_WEBKIT_REVISION are
set, the script will use the value of those instead of trying to pull
the info from the git repository.
Update readme following removal of Web+ from the tree.

 * Web+ is now built in Haiku itself, and this repo only includes the
libs and HaikuLauncher.
Remove obsolete files.

 * These are now part of Haiku service kit, and provided by Haiku as
system headers.
 * The version provided by Haiku also has some bugs fixed.
Remove curl from HaikuLauncher linked libraries

 * Let the WebKit library transitively depend on the network backend,
which can be either curl or libbnetapi.
Fix the way Form data is added to the request

 * FormDataIO added the datza to the request body, not the http headers.
 * Use the appropriate method from the service kit instead.
 * This makes basic form fields working, but not file uploads. Added a
FIXME about that.
