"Data Transfer Interrupted" with websites offering only TLS 1.2 on SHA256/SHA384

[creopard]

Running RetroZilla 2.2 will not work on various websites offering only TLS 1.2 with newer cipher suites:
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027)
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
and just results in a "Data Transfer Interrupted" message.

Retrozilla 2.2 "only" supports according to ssllabs' clienttest
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013)
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014)
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a)
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009)

Is there any chance to add support for TLS_ECDHE_RSA with SHA256 and/or SHA384

Here is a test website: https://www.serverprofis.de/ (SSL Report of that site)

create 2 boolean entry named:
security.ssl3.ecdhe_ecdsa_aes_128_gcm_sha256
security.ssl3.ecdhe_rsa_aes_128_gcm_sha256

and set them to true.

@roytam1: Thank you - it's working great.
Please consider adding these values with the next release of retrozilla!
