Missing pictures for some Yealink devices

I have created two PNG files in the required format and colour highlights for the SIP-T19P phone and the EXP40 keypad, here attached.

I will get the T4x series done shortly, with the correct colour highlights, and attach them here.

For the EXP40 (as with other keypads) I suggest to create soft links to the EXP40-1.png file rather than make multiple copies of the same file with different numbering.
