[imp] Remove some interface table methods

Finally we are going to let this methods:
```PHP 
public function bind($src, $ignore = array()); 
```
```PHP
public function check();
```
```PHP
public function delete($pk = null);
```
```PHP
public function getDbo();
```
```PHP
public function getKeyName();
```
```PHP
public function load($keys = null, $reset = true);
```
```PHP
public function reset();
```
```PHP
public function store($updateNulls = false);
```

We did the list based on the basic table requirements + <code>JHelperTags</code> at:

Please @dongilbert confirm if this is ok for you ....  :)
