Fixes Sublime Text 2 open project odd behavior on Windows by making sure the selected project receives focus. Will also open files in a specific project window.

openSublimeProject.ahk

;
; Opens Sublime Text 2 and makes the wanted project have focus
; If additional files are specified, they'll be opened in the specified project
; Useful for scripting, global hotkeys, command launchers, etc
;
; Example:
; openSublimeProject.ahk c:\sites\blog\blog.sublime-project c:\sites\blog\.gitignore c:\sites\blog\Gemfile
;
; Problems this script fixes:
; 1. If sublime is already open with the requested project, it creates an empty window and makes that active
; 2. If two projects or more are open, the requested project window does not receive focus
; 3. The most recently active window is the one to open a file, which may not be the requested project
; 4. Sometimes the project window isn't made active, a PX_TIMER_CLASS hidden window actually gets focus
