Added support for Auto-login
- Using rc4 to store ssl pword on file for linux, for windows already using cryptprotect - yes its not safe, but its the user's choice to keep pword or not - consider using method closely hooked to linux kernel (another layer of obfuscation) - windows i believe is stronger (because its proprietary/ heavily obfuscated) git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@2690 b45a01b8-16f6-495d-af2f-9b41ad6348cc
