Using "require" fails with precomiled packages

[agbristol]

Hi, I recently tracked down a problem I was having to the line require("Color") in the file Compose.jl. Apparently, calling require("<package>")is known to hang sometimes if the package is precompiled. According to this thread packages should be using include or using rather than require to load modules. I would like to suggest that the lines in Compose.jl which require packages be changed to using or include. I can submit a PR with these changes if you like.

Weird this didn't happen to me. But I precompiled Gadfly, not Compose. @agbristol do go ahead and submit a PR if you can!
