vim_executable isn't read from ~/.floorc

[c0ffeeartc]

When using FlooJoinWorkspace it keeps saying

Your vim was compiled with clientserver, but I don't know the name of the vim executable.
Please define it in your ~/.floorc using the vim_executable directive. 
e.g. 'vim_executable mvim'. Falling back to f//e hack which will break some key commands.
You may need to call FlooPause/FlooUnPause before some commands.

I have ~/.floorc with content

vim_executable vim

For the time being, I hardcoded plugin/floo/vui.py:114 to exe = 'vim' to remove warning
