Add pydiction support, tested under ubuntu. BUT!

Not tested under windows, I think it will has some problems
Merge branch 'master' into f-add-pydiction-support

This is to update f-add-pydiction-support
branch to latest status
in order to do the test on windows
Let vimrc support window's pydiction

Changed pydiction's plugin folder name just
for not changing vimrc if pydiction is updated again
Merge branch 'f-add-pydiction-support'
