Improve vimrc to include more information and settings

+ Add more binds, even if left default, for reference or quick adjusting
+ Adjust sourcerer.vim for ultra-black background
+ Set clang_complete to use snippets for code completion in C / C++
+ Set clang_complete binds jump-to declaration and jump-out to + and _ respectively
+ Add information to vimrc to allow adjusting clang options
+ Highlight column 80 on cpp and c files
+ Revert to unicode symbols by default, left powerline symbols commented out for now

### Install Clang Completion
**These configurations require the installation and setup of libclang for clang completion**
**These configurations require the installation of clang for clang completion**
If you don't want clang completion, just remove the plugin directory from `~/.vim/bundle/`.
If you don't remove clang completion and skip the following steps, vim will show errors when opening source code files. This is because these configurations use clang completion for source code auto completion and drop-down menus within vim.
I use the `libclang-10-dev` package for this. You can use whichever version you want, but to use the same version as I do, you could run the following commands.
Note that the `printf` command may take some time to finish, since it is searching your system for a needed file.
sudo apt install libclang-10-dev
sudo apt install clang
printf "export LIBCLANG=\""$(find /usr/ -name 2>/dev/null)"\"\n\n" >> .bash_aliases
echo "let g:clang_library_path=\$LIBCLANG" >> ~/.vimrc
source ~/.bashrc
