UP-4215 : Add quick deployment tasks

Added in the following ant targets:
* `deploy-less` - recompiles utilizing `lessc` and deploys it to tomcat
* `deploy-xsl` - deploys out everything under `/uportal-war/src/main/resources/layout` to tomcat

In doing this we will not need to do a `deploy-war`. Just think of all the compilation time we just saved.
