Add profile support

README

+======
+Config
+======
+cc-cli support FreeDesktop BaseDirectory specifications (http://standards.freedesktop.org/basedir-spec/0.6/)
+Your main config is stored in ~/.config/cc-cli/cli (ini file format with section cli)
+You can configure all parameter in this file
+You will find an example in examples subdirectory in git.
+
+You can set default behaviour with environment variables. The following are recognised:
+CC_SERVER, CC_PORT, CC_LOGIN, CC_PASS, CC_DEBUG, CC_PROFILE
+
+To quickly connect to mulptiple servers, you can define profiles.
+A profile is an ini config file in ~/.config/cc-cli/ directory with suffix .profile and section profile.
+Profiles file are loaded exactly like the main config file.
+You can load toto profile by calling cc-cli -P toto
+You have to play with the following loading order to do worderful things.
+
+You configuration is loaded in this order:
+1 load default config file settings
+2 load default config file profile
+2 load environment profile
+3 load environment settings
+4 load argline profile
+5 load argline settings
+
+=====
+Alias
+=====
+CLI support aliasing. This is a very useful command substitution
+You can use the alias command to set alias.
+
+Setting an alias w, which list online client
+alias w "list a&con!=offline&role=client"
+
+Setting an alias vm, which list running vm (and show cpu)
+alias vm "list vm&status=running$cpu"
+
