templater: fix if() to not evaluate False as bool('False')
Before, False was True. This patch fixes the issue by processing True/False
transparently. The other values (including integer 0) are tested as strings
for backward compatibility, which means "if(latesttagdistance)" never be False.
Should we change the behavior of "if(0)" as well?
