coreldraw x4 to save in v7 format

[wall]

@sledger: Though a bit tricky, but it (exporting pdf from xara into X4) actually worked! thank you!

@coza: Many local printers here still only accept older versions of corel format. Like you said, probably due to the hardware devices they use...I want to keep the text as text instead of curves, that's why I was fighting with text part...
