Add vim-slime and vim-ipython-cell

Added interactive python repl commands with two plugins:
Sending repl snippets over with vim-slime and interacting with python
(notebook-like) snippets in the editor with vim-ipython-cell.

Cells are simply demarcated by `## ` at the beginning of a line, though
they can have other syntaxes as well, e.g. `# %% `.

By default slime sends its commands over to the last used tmux pane so
it is easy to set up a split coding/repl-ing session.

Interaction mappings all center around <leader>c + another key.
You can send a simple cell with `<leader>cc` or `<leader>C`,
single lines or selections with `<leader>cs`.

You can switch between cells with `]c` `[c` and insert new ones
below/above existing ones with `<leader>co` `<leader>cO` respectively.
