Few error fixes

Hi, thanks for great plugin. I did get couple of errors in debug mode which can be easily fixed.

includes/availabilitybookingfunctions.php
line 195: 'closeText' => __('Done', 'jm_avail_booking'), //added quotes to jm_avail_booking
line 196: 'currentText' => __('Today', 'jm_avail_booking'), //added quotes to jm_avail_booking
line 199: 'monthStatus' => __('Show a different month', 'jm_avail_booking'),

line 208: 'isRTL' => is_rtl(), //previously $wp_locale->is_rtl where is_rtl is undefined

I hope I fixed it correctly. Thanks !
