- Fixed subl search path order in Mac because Sublime Text 3 is named
  Sublime Text.app by default instead of Sublime Text 3.app and they are
  mostly likely to be placed in /Applications instead of
  $HOME/Applications.
- Fixed sublime text binary path in Linux. The sublime_text binary
  installed by Ubuntu installer is placed in /opt/sublime_text/sublime_text
  instead of /usr/bin/sublime_text.
- Use zsh's built-in process detach syntax instead of nohup.

The typical command is `subl`, not `st`. Leaving both for backward compatibility.

See http://www.sublimetext.com/docs/2/osx_command_line.html

User changed symbolic link for sublime binary is now top priority,
since this allows users to actually specify which version of sublime
they want to use. Sublime text 2 binary has higher priority over
sublime text (3) binary, since sublime text 2 is considered more
stable.

updated run sublime on linux with parameters 

Considering the situation when installing sublime text via apt-get (WebUpd8 Sublime Text 2 PPA)

Detects the platform using "uname", and sets the alias accordingly.
If you are using Linux, this assumes that you have created a
symbolic link to /usr/bin/sublime_text.
