Improved Xcode support

Improved support for Xcode via a new version of file: go/misc/xcode/go.xclangspec

What steps will reproduce the problem?
1. Use Xcode to edit/view Go source files.
2. raw strings are not parsed correctly by Xcode, e.g.go/src/pkg/go/scanner/scanner.go
3. type and function definitions do not appear in the pop up menu.

What is the expected output? What do you see instead?
Xcode does not highlight quotes in raw strings correctly.
Xcode does not put top level declarations in the pop up menu.

What is your $GOOS?  $GOARCH?
darwin amd64
Xcode 3.2.1

Which revision are you using?  (hg identify)
a6fcf4303b0a release/release.2009-12-22

Please provide any additional information below.

I've made the following changes to go/misc/xcode/go.xclangspec
Item 0. Added "." as an identifier character, to support qualified names.
(Cleaner fix might be to
define qualified.go.identifier, etc.)
Item 1. Added "*" and "," as Interesting.Operators. Needed to parse
pointer types and parameter 
lists.
Item 2. (New) Added a definition for xcode.lang.go.rawstring This fixes the highlighting 
problem.
Item 4. Added xcode.lang.go.rawstring to IncludeRules for xcode.lang.go.lexer
Item 5. Added xcode.lang.go.method.declaration and xcode.lang.go.function.declaration to
the 
Rules for xcode.lang.go.lexer.toplevel
Item 6. (New) Added a definition for xcode.lang.go.method.declaration
Item 7. Changed the Type of xcode.lang.go.type.declaration to xcode.syntax.typedef
Item 8. (New) Added a definition for xcode.lang.go.function.declaration 
These two changes allow methods, types, and functions to appear in the pop up menu.
Item 10. Added xcode.lang.go.block to the IncludeRules for xcode.lang.go.parenexpr
This allows the parsing of interface types in parameter lists.

I did not attempt to handle const or groups of definitions; or make a more complete
attempt to 
describe the Go language.

Comment 5 by kenliz@cruzio.com:

I followed the instructions at http://golang.org/doc/contribute.html
for submitting code. But it turns out that the mail messages generated by hg mail to
golang-dev get 
blocked. Worse, my ISP filtered out the "Delivery Status Notification (Failure)"
messages as spam, so I would 
not have known, except I happened to review my weekly summary of spam, and noticed them.
Should I open another Issue about this?
Here is the relevant content of one of the bounced messages:
Hello xxxxxx (removed e-mail addess, Ken)
We're writing to let you know that the group you tried to contact (golang-dev) may not

* The owner of the group may have removed this group.
