allow quotes in conf values

[Jamiras]

Description

Any string written to retroarch.cfg containing double quotes will now explicitly escape the double quote. Other characters are not escaped to prevent breaking of things like paths. When reading the config file, a \" pair will be converted to ". Any other backslashes will be treated as single characters.

Before:

cheevos_password = "it's a "secret"."

Would be loaded as it's a .

Now, it will be written as:

cheevos_password = "it's a \"secret\"."

Which will retrieve the full it's a "secret"..

Other instances of backslashes are not escaped.

rgui_browser_directory = "C:\Games\ROMs"

Small tweak in Jamiras#10

[Jamiras]

Thanks for the feedback.

I've modified config_file_strip_comment to handle escaped quoted values. Tested with:

"se\"cret#1"

and

"This is a \"Secret #word#\"" # ignore this

And incorporated a modified version of your solution to ignore the last escaped quote if no further quotes exist.

Solid.
