incorrect URL and updated references to ':Bundle' commands to ':Plugin'
commands

The setting of the default values for the autoload variables is moved out of
any function.  One reason being that these settings do not depend on the
argument of the function.  The second being that Vim will source the autoload
script if an undefined autoload variable is referenced and the file is
expected to define the variable (see :help autoload).

All global variables that are not part of the public API (mentioned in the
documentation) are turned into autoload variables.  This is intended to give
all global variables defined by Vundle.vim a common prefix.  The variable
g:default_git_proto is part of the public API and is therefor not changed.
This is the only exception.

Changed:
   g:bundle_dir            -> vundle#bundle_dir
   g:bundles               -> vundle#bundles
   g:updated_bundles       -> vundle#updated_bundles
   g:vundle_lazy_load      -> vundle#lazy_load
   g:vundle_log            -> vundle#log
Unchanged:
   g:default_git_proto

The variable is script local to autoload/vundle/scripts.vim since #468.

* Add modelines to all code/doc files excluding README.md.  The modeline used is: `" vim: set expandtab sts=2 ts=2 sw=2 tw=78 norl:`
* Rename links with /vundle to /Vundle.vim, seems to confuse some people with redirect.
* Remove duplicates from Quickstart, add example of `name` flag.
* Add link to Tips page by @Lucc .
* Change help maintain vundle link directly to the new one.
* README.md line number links updated.

Note: Users with bundle/vundle need to rename vundle to Vundle.vim to use test files. Vundle will continue to function otherwise.

Fixes #413.
Fixes #438.

It's a duplicate of the PluginSearch command.

Fixes #428

Also add some FIXME markers in places where the code needs more
explanation.

New supported option called 'pinned' for the Plugin command. When set to
1, the plugin is added to rtp but no install/upgrade operation is
performed.

It not only allows vundle to do rtp management of plugins on VCS other
than git, it also allows leaving plugins that had previously been
managed by vundle in the current state, with no further updates.

Fixes #24, #397

Still keep :Bundle backwards compatible.

- closes many issues )

'BundleUpdate' is a more intuitive and explicit command, whereas 'BundleInstall!' isn't.

- as before Helptags returned 'updated'

Keeps track of the current commit with a vundle_update tag before
perfoming an update and adds all commits pulled in the update to a
Changelog accessible via pressing 'u' after BundleInstall! completes.

- closes #110

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