Allow udev rules to be configured at build time [#25] 

Prior to this change, the udev rules were fixed to allow read-write
access only to the `plugdev` group. However, while this is the default
group for USB input devices on Debian and its derivatives, this is not
true for some systems such as openSUSE, which use `input` as the group.

This change adds a `--with-input-group` argument to `configure`, which
defaults to `plugdev`. This change also updates the install
documentation to reflect the new options.

make && sudo make install

## Configuration options
### udev
The configuration system should automatically detect the udev rules directory,
but you can override it by using the following argument to `configure`:
```
--with-udevrulesdir=/path/to/udev/rules.d
```
### Input group
The udev rules that are installed provide read/write access to members of the
input devices group. This defaults to `plugdev`, but can be modified using
the following argument to `configure`:
```
--with-input-group=group
```
