This patch includes an added plugin for a VowelShift cipher that detects vowels and shifts them by an integer value (as such, it virtually ignores consonants).
For example, given a key '1', 'e' would become 'i' and 'o' would become 'u', giving that "hello" would become "hillu".
*NOTE: This patch does NOT include the NullShift cipher plugin.
