Title: rails4: Bump jeweler, ruby-plsql and ruby-oci8 gems to the latest version

To execute Oracle enhanced unit tests with rails4 branch, the jeweler gem is required.

```ruby
$ rake spec
rake aborted!
cannot load such file -- jeweler

(See full trace by running task with --trace)
$
```
In addition the old version of jeweler does not work with bundler 1.1.3, which is installed with ruby 1.9.3.

```ruby
$ bundle update

Bundler could not find compatible versions for gem "bundler":
In Gemfile:
jeweler (~> 1.5.1) ruby depends on
bundler (~> 1.0.0) ruby

Current Bundler version:
bundler (1.1.3)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
$
```
This pull request also bump ruby-plsql and ruby-oci8 to the latest version.
