Compress files on add instead of using Phar::compressFiles (fixes #80)

[remisauvat]

Apply file compression when adding a file instead of using Phar::compressFiles at the end. This avoid the issue of opening too many files.

On my project the build even runs faster for ~1200 files.

Tests with compressFiles:

Building...

real    0m23.524s
user    0m14.499s
sys     0m8.972s

New version with compress on the fly

Building...

real    0m19.612s
user    0m10.440s
sys     0m9.135s

Hoping this will get reviewed soon and merged into next release. Since I am restricted to using the Phar file release, I have had to disable compression in order to allow our project to build which has increased the resulting phar file size by 600%

I'm not really convinced of the results: https://github.com/humbug/box/pull/29

Did I miss something?

I cannot access the blackfire graphs. Can you upload a screenshot ?

Damn, looks like I accidentally deleted them. I'll redo them tonight

Still the link here https://github.com/humbug/box/pull/29#issue-290215315 give a 404 not found

Should be fixed, I forgot to make them public
