printstatic no longer needed

a basic version of the sheet that is printable can now be found at
show.php?target=print
This does not mean that printing is ready.
Save / Load mostly implemented

Save and Load functionality partially implemented. SAVE with the save
button at the bottom of the sheet.
Note: No "fluff" details are saved at this point. (See #29)

LOAD with show.php?character=X where X is the UID of the character to
load. (see #28)
