Fixing issues

1) If the properties file contains more than 2048 words for translation , the app was failing
2) also parsing letters with ${} as a part of html , for ex: <a href='#' > ${} </a> will be changed to <a href='#' > <span class="notranslate"> ${} </span> </a>
3) ignoring ${} present in attributes of html elements , for ex: <a href="http://${app_nm}/"> </a>
