Template engine fixed:

Template engine fixed:
- Template engine does now not compile the code, this is required for loading
  extension's description templates and maintaining the embeded EL code. This
  will make sure that configuration entries and other "dynamic data" can be
  inserted on execution time and not on compilation time.
- Some extension's description templates still had {?foo_bar?} EL code instead
  of {OPEN_CONFIG}foo_bar{CLOSE_CONFIG}. The first one would insert
  configuration data on compilation time, the second on execution time.
- TODOs.txt updated
