This is such a shame to hear and must be very disheartening for you.
First of all I would suggest that if the present trend of wet summers continues, growing tomatoes outdoors will be a thing of the past.....the spores of blight flourish in warm damp conditions. Growing in a greenhouse does give some degree of protection as the foliage remains dry for the most part.
The only advice I could offer is to grow blight resistant varieties in future (Ferline by T&M is a reliable one) and keep your greenhouse well ventilated.
Btw, Your greenhouse will need a scrub-up with Jeyes Fluid before you plant with tomatoes again and *fumigate using a sulphur candle just before planting.
*Make sure the greenhouse is totally empty before fumigating.
