fix for windows spaces, needs testing

[ofZach]

this is a potential fix for this issue:

#77

needs testing...

[ofZach]

this doesn't seem to work :(

but this seems to help:

if( arg.platform == 'osx' || arg.platform == 'linux' || arg.platform == 'linux64' ){
    pgApp = pgApp.replace(/ /g, '\\ ');
} else {
    pgApp = "\"" +  pgApp + "\"";
}

open in IDE seems broken, digging into this...

this works well for me on windows path with spaces (open in ide works now, generating works)... going to check osx then merge.

this seems good on osx now (open in IDE on osx was broken but is fixed now...)
