Need to store profiles in version-specific path under home dir

[dob71]

Storing profiles with the installation isn't right.
Current thinking:

• use version-specific path under ~/.x2sw;
• clone the profiles repository under ~/.x2sw/ from either local or remote (or fetch changes if already there), check out and make everything use the files under ~/.x2sw/ as well (i.e. all components will have to figure x2sw version);
• change profiler to allow user create and store custom profiles right in the repository under ~/.x2sw/ (there's another issue for that).
  This will make it impossible to use 2 x2sw installations of the same version using different sets of profiles, but as long as it is just a few button clicks to pull out the needed one from the repository it's probably ok.
