Template stability fixes

[ghost]

Hi. Thanks for the good work.

I suggest few small changes to make the generated template functions more stable:

Add newlines (\n) before "out+=", this allows the templates to contain single line comments (//), otherwise these comments are carried in the generated function code thus breaking it.

line 134:

for ( var m=0,l=arr.length; m < l; m++ )
str += arr[m].charAt(0) !== '\x1b' ?
"\nout+='" + arr[m].replace(/(|["'])/g, '$1') + "'" : (arr[m].charAt(1) === '=' ?
';\nout+=(' + arr[m].substr(2) + ');' : (arr[m].charAt(1) === '!' ?
';\nout+=$.jqotenc((' + arr[m].substr(2) + '));' : ';' + arr[m].substr(1)));


Add check for null and undefined values in jqoteenc. Without this check jqotenc crashes on null and undefined values because they don't have .toString() method. I guess booleans will crash too, but I haven't tested this.

line 168:

jqotenc: function(str) {
if(str === null || str === undefined) return '';
return str.toString()
.replace(/&(?!\w+;)/g, '&')
.split('<').join('<').split('>').join('>')
.split('"').join('"').split("'").join(''');
