SingleFileUpload does not consider javascript callbacks

[openfaces]

[Florian Jung]In the current SNAPSHOT the single file upload component does not consider the settings for

• onfilestart
• onfileinprogress
• onfileend
• onwrongfiletype

as in the component's renderer class SingleFileUploadRenderer line 257-260 the events are named in an inconsistent manner.

When in the class renamed to

• filestart
• fileend
• fileinprogress
• wrongfiletype

the component works as expected.

Sorry for not delivering a patch file as I have no glue which branch is the one the snapshots originate from.
