[TYPO3-core] FYI: Removal of plupload javascript files

[Steffen Kamper]

Hi,

i removed 2 remaining javascript files from plupload which was forgotten 
to delete.

4_5 rev 10474
trunk rev 10475

As it turned out that pluplad is very buggy and not real cross-browser 
working, i will have a look to awesomeuploader in near future, it sounds 
well from description, may be you already know it.

vg Steffen
