expand ~ when loading global path

[rcorre]

If c.global_path specified in consularc contains a '~', it should be expanded. I noticed that if I specified c.global_path = "~/path/from/my/home" in my consularc, consular would fail to load my project files claiming that "~/path/from/my/home" doesn't exist (even when it did) because it wasn't expanding the '~'.
