Fixed issue with filename parser for 9 patch images

[Issue#]       N/A
[Problem]      .filename9.jpg or .filename#.jpg matched incorrectly.
[Cause]        matcher not stopping if not detected . before 9 or hash.
[Solution]     Ensured matcher stops after character before 9.suffix or #.suffix.
Note, the filename ".9.jpg" still matches - is this desired?
