Issue #254: support exclamation point as ending char in path

[tparsioan]

This addresses the issue in 'extractUrlsWithIndices' function where it does not properly recognize the full URL if the ending character in the path is an exclamation point (!). With a URL as such: https://www.domain.com/locale/#!?key1=value1&key2=value2

The complete URL 'https://www.domain.com/locale/#!?key1=value1&key2=value2' will be recognized as a URL instead of just the part preceding the exclamation point 'https://www.domain.com/locale/#'.
