Plugin to keep certain registers (specified by the global variable
g:localRegisters) specific to individual filetypes.  For example, if editing
a Java file in one window and a Vim script in another, one may want to
search for a variable name in the Java window that has no bearing in the Vim
window; however, ordinary functionality would clobber the Vim window search
register value, requiring the use of search history if the original
expression was complicated.

This relies on my getVar.vim (vimscript #353).

Mappings (default):

<Leader>im -- used to import one register from another filetype

Commands:

Copyregister -- used to import one register from another filetype (the
mapping just executes this command)

Customizations:

By default, no registers are localized (so no behavior changes should be
noticed).  To localize registers, place an assignment to g:localRegisters
inside your _vimrc:

let g:localRegisters="abcm/"

The above allows registers a, b, c, m and the search register to be
localized based on filetype (all Vim scripts get one copy, all Java files
another etc.).

To change the default mapping for importing register contents from another
filetype, create a normal mode mapping to <Plug>CopyRegister in your _vimrc.

TODO:

- Keith Roberts:  Allow certain filetypes to retain global settings through
  the use of an option (set through an ftplugin, for example) -- these would
  inherit the settings of the last window, in all likelihood, rather than
  setting their own.

- Maybe allow certain filetypes to ALWAYS keep in synch with others?
