add automatic conversion of dot values in data, to remove "pathsep"

[perfecto25]

data comes in with unexpected chars,

ie

data = {"/tmp/file": "true", "file.conf": true"}

this data has to be parsed with pathsep="some separator", as dot and / wont work, both "/" and "." are in the lookup path

makes using pathsep impractical because any character used as pathsep can actually be in the data string

add auotmatic splitting to insert some unique separator that wont ever come up in actual data , ie "dictor_sep" or something similar, that way users wont ever need to use pathsep flag
