Changing cccam default reshare_mode to 4

does reduce unwanted reshares in cccam.

Corrected setup trough web-if from reshare value oscam.

now -1 also possible. With this it's possible to again set resharing strictly based on reader and or account setting's. Now a specific reader can be eccluded into cccam reshare by having reshare -1 in global and -1 (or blank by reader self)
