Fix smarty syntax typos where {else if} is used instead of the correct {elseif}

I grep'd for instances of the incorrect syntax

{else if}

and replaced with the correct syntax

{elseif}

.

grep -rn '{else if' . | grep -v svn
./Activity/Form/Activity.tpl:269:

{else if $action eq 1 OR $action eq 2}

./Event/Form/Participant.tpl:137:

{else if $participantMode == 'live'}

./Profile/Form/Dynamic.tpl:123:

{else if $n|substr:0:4 eq 'url-'}

./UF/Form/Block.tpl:104:

{else if $n|substr:0:4 eq 'url-'}
