- Added defines script_getnum and script_getstr to further simplify variable reading code.

- Applied mass replacing of text to enforce usage of script_hasdata, script_getnum, script_getstr and data_isstring defines where possible.
- Cleaned up the 'input' command code.
- Minor other cleanups in script.c
- Removed OPTION_SIGHTTRASHER as there's no indication this value exists.
- Corrected OPTION_XMAS since 2007 clients have split it up from OPTION_FLYING (on previous clients both were the same option value)
- Removed GRF_PATH_FILENAME references (it wasn't used anymore)

 AS OF SVN REV. 5091, WE ARE NOW USING TRUNK.  ALL UNTESTED BUGFIXES/FEATURES GO INTO TRUNK.
 IF YOU HAVE A WORKING AND TESTED BUGFIX PUT IT INTO STABLE AS WELL AS TRUNK.

+	* Corrected OPTION_XMAS since 2007 clients have split it up from
+	  OPTION_FLYING (on previous clients both were the same option value).
 	* Corrected statp array not being long enough to actually hold the status
 	  points of ALL levels up to and including MAX_LEVEL. Fixes reaching final
 	  level and resetting giving you an unpredictable amount of status points.
