Default report time for web submissions is almost always wrong

The `$incident_hour` array used by the web report submission forms looks like this:

```php
array (
  '01' => '01',
  '02' => '02',
  '03' => '03',
  '04' => '04',
  '05' => '05',
  '06' => '06',
  '07' => '07',
  '08' => '08',
  '09' => '09',
  10 => '10',
  11 => '11',
  12 => '12',
);
```

However, in application/controllers/reports.php, the default value for `$form['incident_hour']` is:

`$form['incident_hour'] = date('g');`  (12-hour format of an hour **without leading zeros**)

So the resulting value will not have a leading zero, and the form helper never finds a match when hour is less than 10, and always defaults to "01". Probably just a typo ;-).

This needs to be `date('h')` instead, like what is used in `application/controllers/admin/reports.php` and `application/controllers/members/reports.php`.
