Use language strings instead of hard-coded values in xml

[imanickam]

In the file mod_sermoncast.xml, as shown below, the values such as Auto, Audio, and Video are hard-coded instead of using the language strings.

<field name="sc_type" type="list" 
                    label="MOD_SERMONCAST_FIELD_TYPE_LABEL" 
                    description="MOD_SERMONCAST_FIELD_TYPE_DESC"
                    default="">
                    <option value="">Auto</option>
                    <option value="audio">Audio</option>
                    <option value="video">Video</option>
                </field>

In the file default.xml, as shown below, the values such as Auto, Audio, and Video are hard-coded instead of using the language strings.

<field name="type" type="list"
                   label="COM_SERMONSPEAKER_FIELD_TYPE_LABEL"
                   description="COM_SERMONSPEAKER_FIELD_TYPE_DESC"
                   default="">
                <option value="">Auto</option>
                <option value="audio">Audio</option>
                <option value="video">Video</option>
            </field>

This PR will replace the hard-coded options "Auto", "Audio", and "Video" with the new language strings formed that would be consistent with similar implementations.

(a) The following language string is available in the language file en-GB.ini located in the directory \administrator\language\en-GB\en-GB.ini. JGLOBAL_AUTO="Auto" Probably this could be used in the place of the new language strings MOD_SERMONCAST_FIELD_TYPE_OPTION_AUTO and COM_SERMONSPEAKER_FIELD_TYPE_OPTION_AUTO.

(b) I believe that the changes in the file en-GB.mod_sermoncast.ini and en-GB.com_sermonspeaker.ini would reflect in Crowdin.

Thanks for this. I'm going to replace the MOD_SERMONCAST_FIELD_TYPE_OPTION_AUTO one with JGLOBAL_AUTO but rest is fine.

Also, please replace COM_SERMONSPEAKER_FIELD_TYPE_OPTION_AUTO with JGLOBAL_AUTO.

[Bakual]

Yep, did that.
