- show installation destination

- batch process just iterates through the lines and calls specified
action
- individual actions give visual feedback aswell
- allow Helptags command as a part of installation process

- merge with view()
- no need for having both

- log is global array so log can be viewed any time
- log gets written to a defined location ~/.vim-vundle/vundle.log
- TODO: write log changes as they happen

BundleInstall sources the current vimrc in order to reload all Bundles
in order to consider new Bundles that might have been added by the user
directly on their vimrc file. This, however, should not be Vundle's
responsibility, changes in vimrc should not be applied unless it is
re-sourced explicitly by the user.

This makes Vundle use the known list of Bundles for installation.

- but don't like it

- TODO: refactor: extract common code

Installer buffer is marked as modified after each installation. Mark it
as nomodified so that no warnings are shown when the buffer is closed.

- Bundles is not a good name for search
- BundleSearch undeprecated
- TODO: repurpose :Bundles cmd

- otherwise confusing with updated

- blows up otherwise for default vim on SnowLeo

- to display message properly

- > active
- + updated
- . up to date
- ! error

- ! is error
- . is up-to-date
- * is updated

- rename statuses to be:
* error
* uptodate
* updated

- instead writing to file and opening it
- faster and has nicer status name

- TODO unify

- as a cleanup
- TODO: make ESC or CTRL-C break installation
