Changed logging code

[shoaibi]

Defined a function called log() which would take care of adding proper category and message prefix if required instead of appending same data over and over.

Excuse the code formatting issues. I use Sublimt Text 2 and somehow that disagrees with github's way of formatting code.

I think there's no reason to use public function. We started making code DRY, so let's do that on 100% :100: :)

You may also include function from Issue #5 discuss

I recommend you to use PhpBeautifier plugin for ST2. I didn't use it, but try out

I think there's no reason to use public function.

As in: 1- No need to have a log() function OR 2- No need to make log() public?

If its #1 I think using a separate function to add in the repeated category and message prefix information falls under DRY.

Ya, saw that, added that. Shall i make a new PR?

Gonna try PhpBeautifier now and report back. Thanks.

No need to make log() public

I think its better to push it into this branch. I mean, add another one commit to this PR

[shoaibi]

Modified log() to be protected. Gonna delete this request and push directly to main repository.

Tried PHPBeautifer but didn't work well, now using phptidy instead.
