- Fixed useless 'array != NULL' check.

- 'notranslate != NULL' is completely useless, because 'notranslate' is an array, hence removed.
- I interpreted 'SbarInfoScript != NULL' as a typo, since 1)in the next expression inside the condition there's a dereference to 'SBarInfoScript[SCRIPT_CUSTOM]' and 2)'SBarInfoScript[SCRIPT_CUSTOM]' is checked against 'NULL', in line 352, and then dereferenced when introducing 'cstype'.
