[plugins] gemspec files includes all vendor/ files

most plugins have this gemspec **files** specification

```
s.files = Dir['lib/**/*','spec/**/*','vendor/**/*','*.gemspec','*.md','CONTRIBUTORS','Gemfile','LICENSE','NOTICE.TXT']
```

the `vendor/**/*` pattern will include all bundled gems if/when building the gem locally when using the "standard" `vendor/` bundle path config.

for some plugins, some files in `vendor/` need to be included, like the geoip database in the geoip filter or jar files for other plugins.

we could either use other directories for non-bundle gems vendored files like `vendor/data` and `vendor/jar` ? or we could exclude the gems specific directories in `vendor/` :

```

drwxr-xr-x+ 63 colin staff 2.1K Nov 12 2014 build_info
drwxr-xr-x+ 63 colin staff 2.1K Nov 12 2014 cache
drwxr-xr-x+ 2 colin staff 68 Nov 12 2014 doc
drwxr-xr-x+ 63 colin staff 2.1K Nov 12 2014 gems
drwxr-xr-x+ 63 colin staff 2.1K Nov 12 2014 specifications
```

@ph is this files specification normally standard across all plugins and updated with the plugins mass update scripts?

thoughts?
