Package Config Improvements

[trishume]

Some minor improvements to configuration of default packages. I also have a contrib layer coming soon, but it isn't ready yet.

Includes:

• Don't pair single quotes in lisp
• Detect ledger files ending with .ldg (I ❤️ that spacemacs comes with ledger-mode and fish-mode).
• Add a config variable for disabling packages. (added so I could disable jedi, which was broken for me.)
• Remove broken neotree toggle modification (It errored out on activation for me).
• Ignore the python environment created by jedi on install

@trishume Love the disabled packages list, it was on the todo list for the contribution system!
I wonder what's broken in your python env. for jedi, usually installing jedi and epc via pypi is enough, there is a big work to do for the spacemacs dependencies: a makefile with an install rule for each package with external deps would be ideal, it should work on Windows, OS X and Linux.
The neotree stuff is a commit mistake, it is a WIP.
👍

I did the install process for jedi, I think the reason it didn't work is that python on OSX is a mess, at least mine is. There's a version of python that comes with OSX which everything tries to use, and then I also have a version of python that was installed by homebrew as a dependency of some other package. I think it might be installing in one python install, then trying to load it from the other one. So even though I ran the install it says it hasn't installed yet.

Anyway it might be a while before I contribute to anything else since I accidentally broke my emacs after upgrading to Yosemite. I uninstalled to try building with different flags but then it turns out that homebrew can't build properly without XCode 6.1, which isn't really out yet. Once XCode 6.1 is out on the app store I'll get back to work.

@trishume I just upgraded to 10.10 yesterday and I had some emacs binaries to rename again:

• in /usr/bin (OS X)
• in opt/local/bin (macports)

Then install homebrew version as usual (after having upgraded XCode CLI tools in the App Store):

brew install emacs --with-x

It was OK. Only weird thing, the unicode lighters in the mode-line have now the same size as railwaycat version.
For the sake of completion, I use the X version to be able to use i3 as a window manager, OS X just suck as a window manager :-(

@trishume I renamed spacemacs-config-disabled-packages to dotspacemacs-excluded-packages and added the corresponding documentation. Do not forget to update your .spacemacs file when you pull the upstream commits.

I hope you will be able to get a working Emacs again.
