Sqlite::truncate(): Verify `sqlite_sequence` exists before _execute()

`sqlite_sequence` is a dynamic table that's only available when a table in
the database use an auto increment field.  For some cases, eg: databases that
exclusively use uuid for primary keys, this table won't exist and
truncate() call will fail with:

  Error: SQLSTATE[HY000]: General error: 1 no such table: sqlite_sequence
Reduce variable use/duplicate code.
Added/removed newlines to make the code more readable.
Use readline in console when supported

$this->stdin->read(); will use readline if the system is detected to
support it.  In linux, you will be able to use the left and right arrow
keys to edit the current line, use the up and down keys to navigate
history, press ^U to delete the entire line, etc.

Before this, using arrow keys in linux will just spam characters like
^[[C^[[A^[[D^[[C^[[A^.  Useful for "Console/cake console"
Correct style

Potential Fix for LightHouse Ticket #3936

I believe I found a fix for this issue. I am here at #CakeFest2013 and during the #HourOfContribution I ran across this issue.

Currently in CakePHP 2.4 on Line 1522 - 1524 you can see the following code:

@@@ php
if ($label) {
	$optTitle = $this->Html->useTag('label', $tagName, '', $optTitle);
}
@@@

The $label variable here the is the $label array passed into the input method in Sethathi example above. The problem is that the $label array is completely ignored and instead a label is created using the HtmlHelper->useTag method.

I have what I believe is a fix for this issue but it hasn't been extensively tested. I tested against Sethathi example in the ticket and it produced the correct result.

The fix is simple. We detect if an array is passed in and then send it to the FormHelper label method instead of the HtmlHelper useTag method. The FormHelper label methods accepts an options array, so we pass in the $label array.

This will probably need to be fixed for checkbox also

Format to CakePHP code sniffs
Remove a default helper from View.

This goes back to the days of yore and combined with
b8320fdbb7fc83d3d9e2b72cd418cf82ae52fdae it causes issues. The specific
issue at hand was testing a helper that uses other aliased helpers
(HtmlHelper specifically). The core helper would always be loaded
instead of the aliased one.
