Partial fix for finding hook executables

This allows, at least, more executables to be picked up.

It doesn't pick up group-executable scripts and ignore xattr files but
it should be better than what was there before.

Closes #80
Link to the openSUSE (and RHEL and CentOS) package

This project is now a part of openSUSE, which can provide easy-to-use
packages for RHEL and CentOS. Link to that.
mkrc with relative filenames inside dotted dir

This is best explained with an example. If I want to track a file like
`~/.bundle/config`, the correct way would be:

    ~$ mkrc ~/.bundle/config
    --> ~/.dotfiles/bundle/config

But if you are already inside the directory, say:

    ~/.bundle $

and you ran:

    ~/.bundle $ mkrc con<TAB> # for autocomplete
    ~/.bundle $ mkrc config
    --> ~/.dotfiles/.config

Which is obviously not what you meant.

This basically checks first if the file exists in the current working
directory and if it is, it's expand the full path.

    ~/.bundle $ mkrc config
    --> ~/.dotfiles/bundle/config
Remove duplicate NEWS entry

This merge conflict was not handled perfectly, apparently, because we
got the same entry twice in `NEWS.md.in`.
Update the copyright, assign it to thoughtbot

This is a thoughtbot project now, so assign copyright to thoughtbot.
Hello world, in Haskell, compiled by autotools
Some option parsing progress, and make failure

- Move files into an `Rcm` directory instead of `src`.
- Re-write the unix `getopt(3)` function because that doesn't seem to
  exist already.
- Implement the very basics of a command-line tool: parse some
  arguments.
- Can no longer build the program using `make lsrc`. Seems like it
  cannot find `System.FilePath` when I try.
Get lsrc built again

- If the file with `main` in it isn't a module named `Main`, you have to
  specify `-main-is` to GHC.
- Something in `System.FilePath` doesn't work under the way I'm
  compiling this. Should figure it out later.
- Add a `Makefile.am` for `Rcm/` so that one can `make clean`.
Learn about -package

If you use a package that ghc doesn't guess about, be sure to list it in
`GHC_PACKAGES`. The issue with `System.FilePath` was around the missing
`filepath` package.

See `ghc-pkg list` for a list of packages, and
http://www.haskell.org/ghc/docs/7.0.4/html/libraries/index.html for the
list of packages that come with ghc.
Some tests

- Test-after development.
- Uses hspec.
- No cabal file or documentation yet.
- Split Lsrc off into a private module.
QuickCheck for handleOpt

Property: passing a option argument to `handleOpt`, it augments the
existing list for the respective `Config` field.
A quickcheck for at

The `at' function produces `Just` when the index is within the list, and
`Nothing` otherwise.
Check for afterElem

Selecting the element after the first element gives either `Nothing` or
`Just`, based on whether there is such an element.
Tests for getOpt
WIP: Get the files

- Introduces a `Rcm.Private.Data` module.
- Introduces a POSIX dependency.
getDotfiles produces all the rc files for a config

- Errors are simply printed for now.
- Adds an `isDotted` convenience function.
An lsrc that can list all files

This does not yet exclude host-specific, tagged, or excluded files.
A richer dotfileTarget

Introduce a `DotfileTarget` type, which stores all the components of a
dotfile separately: the base, the path relative to the base (if any),
the file name, the tag (if any), and the host (if any).
Generate the dotfile source

This is the home directory plus a dot plus the path to the file. Data
structures make this easy.

TODO: `Rcm.Private.Dotfiles` chains `config` throughout - would be great
to get that into a `ReaderT`.
Fix build infrastructure to work with tests

- Move `Rcm` and `Test` under `src`.
- Add a `src/Makefile.am` that knows how to build Haskell.
- Update the test helper to have `src` in its path.
- Re-enable the `bin` directory, but disable `bin/lsrc`.

The tests fail, because the output is still debug output. This is
expected.
