Source code migration to PHP 5.3 features

As soon as minimal supported PHP version of PHPWord is 5.3 for now, it would be really cool to refactor source code and use new features (namespaces, for example).

Migration guide from PHP 5.2.x to PHP 5.3.x could be found here. Tasks to do:

• Replace split() function call in PHPWord_Shared_File class with explode() or with preg_split() function call.
• Implement namespaces support.

@Progi1984, @gavroche, do we plan to do something like that?

Could you open an issue to PHPExcel ?

It's the reference for PHPOffice projects.

Link : #40 (comment)

Sure, but there is small problem with that. PHPExcel still currently supports PHP 5.2. :)

It seems the topic is not actual for them.

[Progi1984]

Yep but the version 1.7.9/1.8.0 is the last one to support this.

The next version 2.0.0 will support from 5.3.0.
Reference : PHPOffice/PHPExcel#183

There is still no answer from PHPExcel team.

@Progi1984, I suggest starting to support PHP 5.3 features independently of the PHPExcel project. php.net announced 5.6 alpha version not so long ago. We can't wait anymore. We're losing time and opportunities. It's time to discuss PHP 5.5 support, but we are stuck with 5.3 still. :(

What do you think?

+1 for not waiting for PHPExcel. If both projects agree to fellow the PHP-FIG standards instead of the PHPExcel standard they would get more support from the community and they could move faster.

@RomanSyroeshko || @gabrielbull : Would you take care of this issue (that I link to #77) ?

[gabrielbull]

Can you merge #76 and #78 in develop before?

[Progi1984]

@gabrielbull Could you point these pull requests to the develop branch, before ?

Guys, do we have some exact dates for our milestones (0.7.1, 0.7.2, etc.)? I have already made some commitments, but I can't promise to do more, because I have no even preliminary schedule. :(

@RomanSyroeshko :
Milestones are composed issues. Actually, in the 0.8.0 (https://github.com/PHPOffice/PHPWord/issues?direction=desc&milestone=2&page=1&sort=updated&state=open), we are at 48%.

New tickets are reported to next milestones, except simple questions.

So, we plan to release each version just when it ready (no time expectations), right?

[Progi1984]

Affirmative. It's why i try to not load each milestone.

OK. I'll take care of this issue, if @gabrielbull leaves something for me to the moment when I handle my earlier commitments. :)
