Cleaned up, and added some error-checking to the CARCodeAddEdit::SaveCheatData() function which deals with the parsing (and decrypting whenever needed) of lines of codes entered in the Add/Edit AR code dialog. 

I believe this makes Dolphin more reliable than GCNcrypt v1.1 which seems to add (prepend) a buggy line when decrypting...

- Split lines using SplitString() once more (as done with ' ' and '-' already), instead of relying on find() and substr() and the (size_t)line variable.
- Rename some variables, use a for() loop instead of a while() loop.

- Apply the StripSpaces() function to each line before attempting to parse them as encrypted/decrypted AR code lines.  Without this, lines such as "B1PD-DXRQ-GTRKM " (notice the unexpected space character) would be recognized neither as encrypted nor as decrypted, which could result in badly decrypted codes (a problem I had tried to explain here: http://forums.dolphin-emulator.com/showthread.php?pid=153532#pid153532).

- For the sake of error-checking, after pressing OK, throw a warning in the following situations:  when a line of code is not in a valid encrypted or decrypted format, and whenever the resulting decrypted code doesn't contain any lines.

(did I do any mistakes?)
